I was very disappointed with my experience at Zengo. I made reservations to take my fiancee for a a belated Valentines day and the experience was horrible. We got there at 11:45am for all you can eat brunch and the waiter told us that we could only order once because they were so busy. We were also told that about one quarter of the items on the "all you can eat" brunch menu were no longer available. So, we ordered our drinks and our food and our waiter forgot half of our order! He was very unhelpful and just made us feel like we were bothering him. He hardly waited on us, brought us "unlimited" drinks twice, which were incredibly watered down and old. We tried to find our waiter to explain that half of our order was missing, but it was clear that he just wanted us out of there, so we got our check and left. I've been to Zengo before and other Richard Zandoval restaurants had such a wonderful experience and the food was excellent, that's why I brought my fiancee here. But the experience was so bad I was simple embarrassed by the horrible service and that we didn't even get all the things we ordered. It was the worst brunch experience I've had in DC. Period. I'm never going back here again and will warn m y friends about it.
