Ate there for the second time yesterday. Each time it was with a group, this time with 14 others. Staff handled our orders professionally and without any problems both times.
First thing I want to say is how fantastic their salsa is. Everyone gets their own small dish so they can add any amount of heat from the bottles of hot sauce on the tables, or double-dip all they want. If you run low they happily refill. And if you ask, they have a wonderful special hot sauce that really sneaks up on you. If it wasn't for the food, I could munch on their chips and salsa all day.
I have not had a bad meal at Cozumel. There were no complaints from anyone else in my group, on either visit, so that constitutes probably over 30 meals without a problem. One person I noticed actually ordered two meals so they could take one home for the next day.
Margaritas are good. Strong. Tastey. Check for the "Special of the Month" at the entrance.
I plan to return.
