Neat place. Took a group of 15 for an after work event. Between the $200 table fee and the 4% coordination fee plus a very high minimum spend requirement, I can not recommend this place for large groups. Food was good, but not spectacular for the price. May be a good date night for couples or small parties, but not good for groups.

My mama drank her margarita till the straw told her there was nothing left! It was our first time here and we had the best server! Her name started with a J (so sorry we forgot) she was so friendly and helpful with everything! Food was quick and really good definitely will return!

It's nice to sit on the River Walk. Otherwise, this place is overpriced garbage, and the server never stopped hounding us about additional things we could pay for. In the middle of our dinner, he literally walked over and said, "ignore me if you want, but I'm going to tell you about our desserts," and then launched into a long-winded spiel about desserts while we weren't even halfway through their disgusting dinner food. But, hey, good margaritas.

For all my Celiac friends out there, this place is amazing! 10/10 recommend. Chips are GF with a dedicated fryer, the salsa is delicious and the queso (GF) is the best I’ve ever eaten. The chicken enchiladas are GF and absolutely delicious as well as the chili lime shrimp salad (the dressing is so good)!! Great atmosphere located right along the river and the staff was well educated on Celiac to avoid cross contamination.

I don’t ever review this low but service is important for me. The food was delicious, vibes outside on the patio were great.. but we got food dropped off at 6:26 and didn’t see our waitress again until we asked another waiter to find her at 7:45pm. We would have each had 2+ more drinks probably. I do think it was a hiccup she seemed very new & didn’t know the menu very well. Would ensure to train new hires until they’re ready because we really wanted some fancy tequila but nobody was there to serve it to us. Probably would have spent $250+ more.
The fish main & brisket queso was unbelievably good 😋
