Taste of Havana.

This little Cuban restaurant is in Fountain City (which doesn't have its own designation here, btw), and it serves up some of the very best food I've had in a long time -- at very reasonable prices.
Reminds me of the food my Puerto Rican grandmother used to make, except for the sandwiches, which are wonderful. Best sandwich bread ever -- thin, crisp crust, tender inside texture. Lots of rice and beans (so far, I've only had black beans and rice, which was extra-good). The desserts are sinful, and unlike anything you'll get anywhere else in town.
Last time I was there, the place was full of Spanish speakers, who looked Cuban to me. I took that as a good sign.
This is a really fine casual dining restaurant; family-owned, good, friendly service, clean as a whistle. It's located just S/W of the Smithwood corner, down toward Broadway, across from Leo's Cafe.
