    We have always enjoyed coming to Abacus, but The service this time was very un-attentitve (especially since he had a 10-top next to us. Not to mention, you called us regarding our anniversary and made sure that names were spelled correctly and then it was never even mentioned or anything done for the anniversary. Also, we were asked if we had paid for our bottle of wine, instead of asking the bartender. Not so wonderful this time

    Had the privilege to eat here over the weekend with a few friends. We all ordered something different and did not have a bad bite of food among the four of us. The lamb was amazing, the bone-in filet was perfect. The mac and cheese was amazing. The caesar salad was unique and also fantastic. My month is watering just thinking about the food. Can't wait to go back. Only negative comment would be on the ambiance. It's not the most appealing layout.

    Steve was our waiter the other night, and I was really really impressed. His service skills were top notch, and was very knowledgeable with the wine list (which is AMAZING). My friends and I all know a good amount about wine, but we really couldn't decide because everything on the wine menu is notable and excellent. Steve helped us narrow it down. Get the lobster shooters - they're out of this world. Sushi and sashimi were excellent, as were our meat courses as well.

    A lot of hype surrounding this place and the only thing that delivered was cost. Food was average and foodies may be disappointed. Nothing really blew me away to match the hype. Service was ok except I got charged the wrong table twice. Wine list good. Its pretty loud so if you want to talk and have a great meal, Save your money, there is much better in Dallas.

    We went here for my boyfriend's birthday and had a lovely, lovely experience. We tried a few of the specialty cocktails, including the Big Daddy, Ginger Basil Gimlet, Gin Gin Mule, and some kind of great peach and whiskey cocktail. We recommend all of them! The food was absolutely wonderful. We had Big Plates with lamb and salmon after starting with the lobster shooters and calamari. To finish we had a chocolate dessert, as well as some sort of pineapple cake brûlée. Everything was cooked perfectly, and Chef Rathburn and his sous chefs even signed a menu for the occasion! I'd love to go back on a weeknight to try the menu with wine pairings. Overall, a wonderful experience, and I will most definitely be coming back!

    Went to Abacus for the first time, and had been looking forward to it for quite sometime. Knowing that Kent Rathburn is such a prestigious chef and has as won the Iron Fork, the food was right up to my expectation if not higher! I don't think I had to open one door for myself, from the valet to the hostess' to the server....the service was just as great as the food! What an exceptional dining experience! Thank you to the Abacus team for giving us such a wonderful experience! We are looking forward to our next visit!

    Ever-changing menu and a most interesting wine lists combine with impeccable service at this North Dallas gourmet staple. Steve was our server and his dialogue from menu presentation, to the meal, to introduction of fabulous desserts made this a memorable evening. Entrees chosen varied from fish to pork tenderloin to duck breast to lamb, all supported by a great bottle(s!) of Crozes-Hermitage at "only" $100 (actually a bargain for that bottle.) Only beef might be that the wine list, while varied and superbly chosen, is a little pricey particularly on the low end. Also not a superb selection of Italian and Spanish wines, although French and California wines are very well and broadly represented. In all a thoroughly delightful evening.

    We went to Abacus a few years ago for our anniversary. After 5 years in the metroplex and experiencing some incredible restaurants in many neighborhoods- so glad we decided to return for another anniversary to Abacus. The atmosphere is so perfect- elegant yet trendy. The service was phenomenal, asking if we wanted to just take our time and enjoy the evening there or move more quickly(thanks, Austi). And the food was amazing. You can't beat the Lobster Shooter experience. Beef tenderloin was perfect, the duck was the best I ever had in any dining experience. Marvelous desserts-Black Forest is my pick. I am so impressed that this restaurant remains on point. Special occasion or a great night out- you can not go wrong with Abacus.

    We recently took a group of 11 coworkers to Abacus. The wine list and menu are always impressive, and this time was no different. Our server was polite and attentive throughout the evening. We started with sushi and appetizers, moved on to soups/salads, then entrees, then dessert. However, the separate courses took entirely too long to prepare, and the group had grown restless before entrees even arrived. About half of the group ordered some type of steak, and every single one was extremely overdone. Mine, which was ordered rare plus, was the only one with pink left in the middle. Our server commented that they appeared overcooked, but given how long we'd all waited, we chose to eat them any way. Another long wait for dessert, too.

    After reading a bunch of fabulous reviews I was a bit disappointed. The menu was extensive. We opted to go for the tasting menu, this way we'd get a good feel for the restaurant. Our 5 course menu consisted of the following: 1. Salmon -- absolutely delicious 2. Scallop -- It was cooked well but unfortunately the bed quinoa that it was on was too crunchy 3. Bison -- pretty good 4. Venison -- gross...the bed of veggies were under cooked and the venison had a gross after taste 5. Hazelnut Macaroon -- It was cute, but not memorable Over all the food was eh... The service - SLOW. I would say a good 15 min to take our order...e a 15 min in between courses which is too long. Service really was not up to par for a highly rated restaurant.

    This visit was during restaurant week, so I didn't have high expectations.

I was very impressed and appreciated that Abacus makes the effort to provide patrons with a great experience regardless of what type of evening it is.

    Abacus might have one of the best dining rooms in the city in terms of vibe, atmosphere, crowd, noise level, and décor. A fun place to be. There was outstanding service even when it's something easy to sacrifice during restaurant week. Ceviche appetizer, beef flat-iron & salmon entrees, and recommended wine pairings were all great. The only surprising let down of the evening was the dessert. Really not on par with the rest of the meal or for a restaurant with the reputation of Abacus. Hopefully just a one time thing. Overall, it was the usual classy dining experience you expect from Abacus. A really enjoyable experience.

    My husband and I took my mother-in-law to Abacus for her birthday. Her birthday falls during restaurant week so it is always a challenge. We were greeted at the door and seated right away, which can be difficult during restaurant week. OUr server was attentive and friendly. He even brought my mother-in-law her own special individual dessert since it was her birthday. My only complaint would be that the buffalo spring rolls were a little greasy. The calamari was fantastic and also the corn soup. My duck dish was wonderful. I wish we could have picked just one of the dessert, as I am not a fan of coconut, but I loved the strawberry shortcake and my mother-in-law loved the smores bread pudding. Other all we had a great time!!

    We were excited to have a chance to visit this highly rated Restaurant. I chose 2 items the waiter highlighted. Both were very disappointing. When did it become "Gourmet" to use GRITS as a base. It looks to me to be the CHEAPEST way to fill a dish and not use fresh vegetables that cost a great deal more. My Salmon over grits was uninspired. My husband ordered the Shrimp. It was similarly adorned but consisted of 3 marginal sized shrimp. We looked forward to the bite sized dessert tray. Again, what a miss. Most restaurants showcase their entrees during Restaurant Week but Abacus seemed to want to get through as cheaply as possible. The positive is the waitstaff and the ambiance but this cannot overcome the poor food and uninspired menu.

The other wait staff were never far away and were always attentive. My friend and I agreed that this was one of our top dining experiences over the last five or six years.

    My boyfriend and I decided to try Abacus during restaurant week, and it was a great experience! We didn't know that during restaurant week, they only serve that select menu, but that wasn't an issue as we wanted to dine on this specific menu for a pre-set $45/person. There were plenty of choices between the small plates and large plates, and we really enjoyed getting the 3 dessert sampler at the end of the meal to share. The lobster shoots were totally worth getting, but would have been a nice free 4th course had I gotten the Central Market certificate. The flavors and portions of the main courses were perfect, and the ceviche was the standout on the small plates. Calamari did not have very much flavor. Just tasted fried, nothing special.

    The calamari was horrible along with the iron steak that had a strange taste, so bad was unable to eat very much of it. To end it all the dessert was not good, what is the point in spending 45 dollars a person if it doesn't taste good at all. Don't see myself going back to this restaurant but definitely will tell people not to go here.

    We really enjoyed the food and service at Abacus. No complaint there. However, when someone called to confirm our reservation, I was told that the duration of our dinner would be about 1 hour 30 minutes. I was quite surprised to hear that since I had never heard of any restaurant trying to get guests out of the door even before they got there. As you would expect, they didn't offer any coffee or tea after our dinner, and we felt we would "outstay our welcome" should we order anything after dinner. While we were enjoying the wonderful food, in the back of our minds, we kept thinking about the time we spent at the restaurant, and tried to finish our meal before our allotted time was up. It sure has made our experience less enjoyable.

    Service and ambience are critical to the overall dining experience. Poor service/ambience can quickly drag the overall dining experience into the muck. Sadly, that's what happened during our visit to Abacus. Upon entering the restaurant (and, not surprisingly, upon leaving) we got the cold shoulder from the maître d. Being warm and welcoming to your customer is the most important job for the maître d, since these interactions provide the critical first and last impressions of your business. While the food was good and our waiter was fine, the ambience was disjointed at best. In sum, we enjoyed better cuisine in Dallas with far superior service and ambience at other establishments, so won't revisit Abacus nor will we recommend it to friends.
