Today was the first time here for my husband and I, and we can say we had an amazing experience. To our surprise, at almost 1pm on a Saturday it was not overly busy and there was no wait time to be seated. The customer service was great, everyone was friendly and nice even other customers around us. The tables next to us got bussed very quickly, everything was kept very clean and presentable. Our food and appetizer came out very fast. The food was so amazing! There was even a young man coming around taking pictures of us (and other tables), printed & framed them and offered them for $20 each photo. Ended up buying 2 framed photos from him! We will definitely be back again soon — it was an amazing experience all together!!

Food was great. We ordered the fish ceviche to start. Was very good and a huge amount. The wife had oyster shooters and I tried the mixed fajitas, chicken shrimp and steak. Shrimp were great flavor and not rubbery! Steak was seasoned really well, chicken was OK. Micheladas are spot on! Our waitress Cassandra in the bar area did an awesome job, attentive and also remembered my wife's crustacean allergy from a previous visit, very impressive. Will be coming back again for sure!

Huge shoutout to Frannie! We had a party of 19 and she made the entire experience feel smooth and stress-free. She was super friendly, on top of everything, and communicated really well the whole time. You can tell she genuinely cares about giving great service. The food was amazing and the place itself was really nice. Definitely coming back!
