Not that the boisterous crowd at La Casita seemed to notice. The little spot was mobbed on the evenings I staggered in, packed to the brim with eager, chattering Mexican-food aficionados. For dessert, they dined on sweet churros, filled with chocolate. Order a round and pass them around the table. Or just skip the desserts altogether. Take a little nap, visit one of the ATMs down the street, and order another margarita. - R.B.
