This tiny four-table cafe may well be Houston's only authentic outpost of Puerto Rican cooking. Yes, the signboard menu still offers up the basic burger fix, but smart customers know to look for the chalkboard with the Puerto Rican specialties of the day. Odd hours (opens at 11 a.m. and closes at 6 p.m.) do little to prevent a steady stream of Houston's Caribbean Hispanics from making their way in. Portions are generous, prices low, and the posters of travel to Puerto Rico a bonus.
