Every Tuesday is Taco Day in salsa-loco San Francisco, with bars throughout the city offering stuffed tortillas to their patrons at exceptionally reasonable prices. The origins of this particular feast day are lost to history, but we do know that Nick's Crispy Tacos and the Underdogs sports bar host the best Taco Tuesday in town. The Baja-style fish taco combines a huge fillet of deep-fried whitefish with plenty of guacamole and all the fixings, served in both crisp and soft corn tortillas to prevent spillage. Three varieties of hot sauce are available to pep up your pescado, and with a bottle of Tecate you've got a fine meal for under $10. Underdogs itself is one of the city's premier sports hangouts, with a long and inviting bar, darts and Pac-Man, conviviality aplenty, and lots of flatscreen TVs for between-taco viewing.
