With brick-sized burritos ($3.25-$3.75), this NoPo institution is known for having the cheapest and largest around�you'll need both hands and a small shovel to get one of these things in your mouth. The tacos ($1.25-$1.50) are a bit smaller and quite tasty, but avoid the Americanized nachos ($1.75) unless you're someone who loves that faux cheese stuff they dump on your food at moviehouses and sports stadiums. But overall, the food is authentic, and Selena's on the jukebox. Enough said. (LP)
