You could live in North Miami for years and never notice it: From the outside, the building — tucked in the corner of a nondescript shopping center — looks more like an orthodontist's office than the setting for a lively Mexican eatery. But wait till you get inside. On any given Friday, patrons of the loud, colorful, delightfully gaudy joint consume tacos the way tailgaters slam down barbecue. Two stuffed soft or crisp morsels come with beef, chicken, pork, steak, or shrimp on either a flour or corn tortilla. Choose from garnishes including pico de gallo, guacamole, chipotle sauce, and sour cream. A plate ranging from $9.95 to $12.95 — depending on your choice of carne — comes with rice and beans. They're tastiest when washed down with a hefty pitcher of margaritas. After dinner, check out the bar, where many a drunken fiesta has erupted. You might wake up with a headache the next day, but it still beats getting your braces tightened.
