You know what you want in a margarita. We'll wager it has nothing to do with flavoring from some rare tropical fruit you can find only on the western shore of Tobago or with weird food coloring (like, ugh, Kelly green on St. Patrick's Day). You want a drink that will cool you down and give you a pleasant buzz, as if the furniture movers in your head finally straightened out the jumble up there. One sip and an ocean breeze is coming through the window and the party is getting under way. That's why you want to get to Yucatan. Their margaritas soften all those sharp tequila corners with Cointreau, Grand Marnier, and the restaurant's own sweet-and-sour mix. Our favorite is the restaurant's namesake, the Yucatan, which is loaded with Sauza Tres Generaciones, an añejo tequila ($6.50). There's also the Golden Margarita with Sauza Comemorativo ($6) and Yucatan's Original Margarita ($5.50). All are available at two-for-one during happy hour, 5 to 7 p.m. Bring a designated driver.
