The Tommy's house margarita at Dos Santos gets people in the door, and it keeps those people coming back. One glance around the patio or through the glass doors at all the guests with margs in hand is enough to stop passersby in their tracks. True to an ideal house marg, this one is simple and addictive, made with nothing more than Arette blanco tequila, fresh lime juice and agave syrup. The price is right, and the balance of sweet and tangy is the perfect accompaniment for happy hour bites or tacos all night.
