  • Our Anniversary Dinner

    Dined on 11/22/2014
    This was our 10 year wedding anniversary celebration. Everything was great. They called the day before to confirm our reservation. Once we arrived we were seated promtley at our reservation time. We asked for a more intimate table and were promptly moved. Our server was polite and professional as you would expect. Food was good, nothing spectacular but what you would expect for a high end restaurant. I had the lamb and my wife had the salmon. The executive chief made the rounds as well another fancy dressed. The best part was the gave us a personalized signed menu with our anniversary date and names printed on it. It was a nice touch!

  • Best Food in Years - Well Done Iron Chef,
    MIck
    Dined on 11/18/2014
    The food was amazing. Allen Brothers wet aged 14oz Fillet was the most amazing he steak ever. The lobster shooters had some interesting but very good flavors but could of passed on them even though that is what put iron chef on the map. One of our guests had the braised lamb and it was also amazing. For sides we had the black truffle risotto- and I would return again and again just for this side dish. Omg it was the best black truffle I've had since the last time I was in the Tuscan region of Italy. Speaking of Tuscany, our bottle of Banfi- Brunello di Montecino was as good as I remember from my visits to Montecino. Thank you Mr Banfi and Mr Sangiovesse grapes. Another notable side was the white truffle pomme frittes. Plenty of white truffle oil with what I think was a fine grated asiago cheese on top. This is the best food I've had in years. Thank you Iron Chef.

    Had a limited amount of time before theatre but upon advising staff, were moved comfortably through our dinner without feeling rushed or any deterioration in the unobtrusively attentive service. Easy to see why their Lobster shooters are a signature and all entres were equally inventive and beautifully presented. Wine list is smashing and the subdued sophistication of the space is sumptous. Just make sure you have a substantial 'open to charge' on your credit card!

    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!

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!

    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.

    Dined on 8/27/2014
    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.

    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!!
