The margarita can be downright fun and fratty. It's the perfect cocktail to get wasted on. Purists argue tequilas, rocks, and salts, but we say, "Pull that slushee pump!" We're overjoyed that San Marcos has settled down on St. Marks. Frozen mango, strawberry, and lime margaritas are a mere $5 to $5.50. After trying all four flavors, we recommend the mango; it's tart, never medicine-y, and you can taste bits of the pithy flesh throughout.
