Friendly, fast service. Miserably small servings. My wife's bowl of red chile ($5.99) was flavorful. My bowl of green with meat ($6.49) had so much ground beef in it that I could barely taste the chile. And in both cases, the size of the serving would have been no more than a buck fifty side dish at pretty much any other restaurant in the state serving New Mexican food. I ate mine in about eight spoonfuls.
On the bright side, the restaurant is very close to McDonald's, which you'll need to visit to have any chance of a full tummy. There aren't many restaurants in Cuba, but do yourself a favor and try the others first if you're in town.
