I stumbled upon Luzia's about two weeks ago, and I love it. Granted, there were a couple of cons. Some of the entrees are overpriced (not all). And the first time I went, they were short in the kitchen.
To make up for it, however, the bartender served us a bottle of wine, no charge. He's also Cuban and makes the best mojito I've ever had, as well as incredible champagne sangria. Also - the tapas menu isn't overpriced. Try the croquetas or the jamon serrano and manchego cheese (both are true Spanish favorites). The churrasco is fantastic as well.
I've heard that Luzia's ownership changed hands within the past couple of years...so if you haven't been in a while, go back - the food was great. And I hear they have Happy Hour from 4-7 pm Monday-Friday with free tapas.
Pros: delicious, authentic dishes
Cons: small, a little pricey
