We eat here about once a week. There is something for every kind of budget and I haven't had anything I didn't like.
When I want to splurge, I order the Enchiladas de Cozumel - about $15 and absolutely amazing. For about $8 they have the enchilda plate and I get 2 enchiladas (Beef and avocado) with rice and beans. We primarily like to go at Happy Hour (M-F 4 - 6p.m.) because tacos are $1, and fajita tacos are $1.50. We can eat a full meal for less than $10 for the both of us.
Additionally, this was voted best Mexican Restaurant by Consumer Reports.
