Review excerpt: Though the restaurant takes its name from the main square in Mexico City, El Zocalo isn’t forceful about displaying its Mexican identity: There’s only one sombrero hanging on the wall. In fact, it feels more like an anonymous cantina. Burritos come in two styles, regular or deluxe. The difference — besides price — is that the deluxe option is Tex-Mex-style with sour cream, cheese and guacamole added, while the regular variety is closer to the classic Mexican incarnation, with meat and refried beans. You can choose from the usual fillings of beans, chicken, beef, carnitas (pork simmered in oil or lard), as well as shrimp.
