    The best parts were the cocktails and the service. The food was ok. I had the shrimp diablo and it was cold and kind of soggy. We had the taquitos and they were soft, not what I expected. Overall it was ok.

    Food was really good as were the drinks. Portions were smaller and prices higher. Some of the a la carte items are more reasonably priced.

    This place has a great vibe and beautiful decor. The service was SO BAD. Our server basically ignored us, never checking in, and we waited way too long for even the initial greeting. By the time he finally showed, we ended up ordering everything because we didn’t know when we would see him again. This was 6:30 pm on a Saturday night, but there wasn’t even a crowd yet, the restaurant wasn’t even half full. We had better attention from the bus boy. My husband’s cocktail finally arrived when we were halfway through our meal, completely unacceptable. We likely will not return.

    Very inconsistent. Went a view weeks and had an exceptional meal. Oysters, yellowtail ceviche, scallops and cocktails. I couldn’t wait to return. Whelp, now I don’t think I’ll be returning a third time. The oysters tasted so different, but looked the same, just the wrong proportions of ingredients. Sad that I cannot trust them to be consistent. The bluefin tuna ceviche was fishy and ruined my appetite. The carne asade was over cooked and poor quality meat. I ate 1/4 of it. The sangria had obviously been sitting for too long because all I could taste was the bitterness from overly steeps citrus rinds.
