The point of sale / ordering system is extremely confusing and irritating. We spent the majority of our meal looking at our phones trying to figure it out. This unfortunately ruined our entire experience. We had a few folks at the table who were first-timers to Diego’s and they left saying they’d never return again. Let’s go back to menus and ordering with a server. On top of everything, the food was just “okay.” Probably won’t be returning. Bummer because it used to be so good.

Hi Anonymous. We are so sorry you did not like the ordering system, it is never our intention to have our guests feel frustrated. We have regular menus and you can always ask your server to take your order as many people do. Unfortunately, the staffing crisis is real and on many days we are short handed so we implemented the system months ago. We hope you return and if you do, just order with your server. Happy Thanksgiving!

Four of us tried out Diego's. We really liked the ambience of the place. Three of us got tacos - fish, shrimp, chicken. Two of also had the Costra de Pollo. None of the tacos had much flavor. One person had the enchilladas, also not much flavor. Three of us got margaritas -- house, my wife's, and pineapple. House and pineapple margaritas were very sour. The person who got my wife's margarita said their's was good. Dessert list was underwhelming -- grilled bananas or vanilla ice cream, caramel, ginger spiced cookies. Two people got the ice cream. Two small ginger snap cookies. No caramel to be found.

All in all, really too bad. It's a lovely space but the food and drinks are meh.

Hi Hwyss. Thanks for taking time out to provide us feedback as it helps us improve! We are sorry you didn't know about our new feature dessert, Tres Leches, you probably would have really enjoyed it. The ice cream doesn't come with caramel, but if you choose to return, you can always have it added. We hope you decide to try us out again in the future. We wish you a great holiday season!

This was our second visit, this time with friends. On our first trip, we had various tacos, YUM! This time, the quesadilla, burrito and enchiladas and all were fabulous. Our service was awesome and the atmosphere is great. The only reason I didn't give them 5 stars was because of the margaritas, a signature must for any Mexican restaurant. Of the 4 of us, we tried 3 different varieties, all have fresh squeezed lime which is a nice touch but all 3 were way too tart for us to want to order again. We then tried the ranch water and an Angelina, all very tasty. Food value is definitely there but the drinks are a bit pricey. All in all though, one of our new go-to's!

Responded on November 15, 2021

Thanks for your review Carole. We will check on the citrus and see if it's more tart that usual. All of our drinks are only made with fresh juiced ingredients and sometimes cases differ due to changes in weather. We appreciate the feedback! Our drinks might seem a bit on the higher side because they contain more alcohol. We use a 2oz pour per drink opposed to 1.5oz. We hope to serve you again soon; cheers!

Hi Lokie. We're so glad you enjoyed your experience with us! We understand that some of our menu items might seem pricey, but we maintain our culinary integrity by using only the best ingredients, like non-gmo corn and flour as well as non-gmo rice bran and olive oils. Even our drinks are made with only in-house juiced citrus - nothing out of a bottle! It's the little things that set us apart, but aren't often talked about. We hope you dine with us again soon; cheers!

Unfortunately they are short on staff and you need to order online to get it “delivered” to your table… so completely loses the felling of being at a restaurant where they are taking care of you. I felt like ordering take out…
Then the tacos weren’t awesome either… for a 5-6$ per taco I was expecting more than a bunch of raw veggies with cold off meat/fish… didn’t taste fresh at all.
Definitively not worth it, at least for me :(

Hi Laura. You are absolutely right; we are extremely short staffed and sorry you didn't like our ordering system. You can always order through your server as many guests do.

I really hope this restaurant survives...they have so much going for them and we love a Ucity establishment!! The location is great, decor nice and wait staff/owners are very attentive. The quality of the food is fair - the salsa tasted like spaghetti sauce (too sweet), the guacamole had no flavor at all (had to ask for salt shaker and limes to make it edible), fish tacos were a bit overcooked and the chicken w/crunchy cheese and chorizo tacos were average. Our spicy XXX margs were fantastic - best part of the meal! We really liked the electronic ordering system - was pretty easy to follow and allowed for an efficient/self paced experience (this is the future of dining). I'll continue watching this restaurant and hoping they improve! But if you want stellar tex/mex in Ucity...I'd highly recommend Taco Buddha!

First, the positives: very attractive space, lots of outdoor seating, using paper straws, my husband’s chicken enchiladas were very good, chips were crisp and not greasy, our server was nice and efficient. The negatives: hardly any of the staff (except a couple of busboys) wore masks and other than ourselves, none of the patrons were, tables very close together, I had the veggie enchiladas and thought the baby spinach should have been cooked more, the salsa was too sweet and needed more spice, and it was really, really loud—if we hadn’t been outside we couldn’t have talked or heard our server. It had received a good review in Friday’s paper which no doubt accounted for the busyness.
We may try again after we are out of the Pandemic, but the lack of responsibility of not wearing masks, even though the web site states they are required, was really jarring.

The food was outstanding. You order the food online versus through waiter or waitress. The service was very friendly but could have been a little more attentive- such as checking if we needed water refills- which we did. Once we asked it was very prompt. We had trouble paying the check online- it wasn’t intuitive. The food and drink was fantastic. Highly recommend and will definitely return.

You order all of your food through the website from your phone, and can keep adding to that order as you desire. The food and drink is brought to you by your servers. It was a unique way to dine.

I come here almost once a week and I won’t be back until they get rid of the online ordering system. It completely ruins the experience and the enjoyment of sitting down at a restaurant when now you have to do all of the work. Not to mention everyone’s food comes out at different times, everyone looks antisocial being on their phones, and everything seems so impersonal. If Sean wasn’t there I would have walked out. Not to mention an employee was rude to me when I asked for silverware saying I should have asked for it before my food came out. Every basket of chips I had were all crumbs and made me question what I was actually paying for. I don’t want to spend my whole dining experience on my phone and don’t want to feel like a burden when I ask people if I need anything. I brought guests who had never been there before and they were so disappointed in the experience. I for sure won’t be back until these issues become resolved. This is a shame.

This Mexican restaurant was top class in everything except for its chips and salsa, and my wife and I love chips and salsa. If chips (hard) and salsa (tomato sauce) are not important, then you will love the atmosphere, drinks, and food quality. They are using a unique method of digital service which I'm interested to see if it catches on. Due to there being a lack of labor, you order your food through your phone, and servers drop off the food and check on you, but you don't have a specific "server." We loved it and will go again.

The service was perfect! The staff was friendly, welcoming, and attentive. They were the best part of the visit, to be honest. The restaurant decor is beautiful. The noise level of the music playing was too loud for being able to hear the rest of my party and we felt like we were yelling over it all night. The food was good, came out hot and everything tasted really good. We ordered a pitcher of house margaritas. The presentation was very cute with the floating flower on top. My only criticism is that the $45 price was exorbitant to the taste and quality. The margarita was just okay. I would never pay that price again for this item. Otherwise, the pricing of the food was reasonable for the quality and quantity served. Thank you!
