Esparza's in Grapevine has great Margarita's. If you just want to hang out for drinks try Flight in Grapevine on William D Tate. It's across the street from Silver Fox. flight is part of Ferrari's restaurant but has it's own entrance. They do flights of wine and martini's as well as gourmet pizza's. www.ferrarisrestaurant.com You could do Mi Cocina in Southlake town square and then do Trulucks for drinks and dessert in the bar-they have a piano player on the weekends. Good luck
