This casual Mexican features a vast expanse of tables in a lively interior festooned with crepe-paper streamers and fiesta decorations. Large fish tanks add even more color to the mix. Lunch hours are busy, but evenings find Paco's positively packed with a wide range of diners, from loners to family groups. In addition to burritos and customary combo plates, there's a bevy of meat and seafood selections and fresh tortillas prepared before your very eyes.
