When this once-obscure hole-in-the-wall expanded from a bar and pool room to a big restaurant, it marked the revival of the western portion of Mexicantown. Now Xochimilco is so popular that crowds regularly keep coming in. Plenty of competitors have opened their doors, but Xochimilco is still the top spot for its dependable, consistent dishes. The formula is simple: generous portions of Mexican staples, including tasty guacamole and gargantuan burritos. The price has remained affordable, and people keep coming nightly until 2a for drinks and munchies.
