What started as a takeaway taco stall on the ground floor of a South Beach hostel has morphed into a small empire that now spans the city. Despite it all, Taquiza still draws its strength from the blue-corn tortillas chef/owner Steve Santana began churning out years ago. Today, the standbys remain the standbys. The carnitas (three for $10.50) are delightfully juicy, the al pastor ($12) offer delicate sweetness and smoke, and the chapulines ($15) combine tart spice and crunch with a heap of rich guacamole. Of course, one must never forget the totopos ($7). These chips, best paired with guacamole, are the Mexican equivalent of a croissant — all flake and crunch outside, and pillowy, rich, and moist within. You'll never look at a chip the same way again.
