Avocado Margarita and Bevo Rita at Curra's Grill ($7 / $7.75)
This inconspicuous Tex Mex restaurant is home to the famous avocado margarita. This frozen delight is creamy and tart, with a distinct nutty finish that only fresh avocados can provide. If you like Vietnamese avocado shakes, you'll love this boozy variation. If you're looking for something a little lighter, try the delicately floral Bevo Rita, a bright and thirst-quenching cocktail made with 100 proof Dulce Vida Tequila, St. Germain elderflower liqueur, agave nectar, and lime juice.
Cucumber Margarita at Vivo ($9.95)
Vivo offers an impressive selection of specialty margaritas flavored with everything from tamarind to hibiscus. Their cucumber margarita doesn't skimp on the Herradura Silver tequila. The delicate green flavor from fresh cucumber purée lifted the Cointreau and lime juice. The highlight was their Hawaiian black sea salt rim, which added a pronounced mineral flavor.
Mango Habanero Margarita at Takoba ($8)
Pick Your Tequila at El Naranjo
This Rainey Street restaurant has an impressive tequila and mezcal collection. All of their tequilas can be shaken into margaritas, even if choosing an ultra high-end one may make the bartender cringe. Picking Corzo Añejo ($14) results in an exceptionally smooth sipping margarita with just the right balance. (The $7 house margarita isn't shabby either: light, fresh, and not too sweet.)
Chiango Margarita at El Chile ($7.50)
While we found their Perfect Margarita a little watery, we loved El Chile's Chilango Margarita. This smooth, frozen orange margarita (made with Valenton gold tequila) is kicked up with a sprinkle of housemade chili salt. The sweet citrus and salty spice play nicely against each other.
Rosa Rita at El Arroyo ($6.50)
This Tex Mex greasy spoon serves up a surprisingly tasty margarita. Sauza 100 Anos Blanco tequila is shaken with Grand Marnier and lime juice, along with a splash of prickly pear purée, which provides a lovely berry-pear-like flavor and bright pink hue. This nicely balanced margarita is always served over ice.
Mexican Martini and Silver Fire Margarita at Trudy's ($9 / $8)
This list wouldn't be complete without Trudy's infamous Mexican Martini. The drink is essentially a margarita shaken with briny olive juice, and it's a local specialty. Though the Cedar Door claims to be the drink's original creator, college students and football moms alike will likely point you towards Trudy's, where they serve the cocktail by the shaker-ful. I like to order extra olives to last me through the whole drink. (Due to its size, there's a two Mexican Martini maximum.)
If salt on salt isn't quite up your alley, upgrade one of Trudy's specialty margaritas with top shelf tequila. (The upgrade's free on Tuesdays). The Silver Fire Margarita is bold concoction made with Dulce Vida Bianco Tequila, Cointreau, lime juice and agave nectar. Fresh jalapeno and a splash of Tabasco adds a pleasant kick.
