Get your mind out of the gutter: It's Double D's because it's in the Design District. The vibe here is the best party you ever hosted in your grandma's basement, with polished brass knickknacks, old couches, a shag rug and the rest. The cocktails here are serious. Try Edna's Lunch Box, a tribute to the famed Oklahoma bar, made with a Miller High Life, amaretto and orange juice served in an ice-cold mug. It oddly tastes like Dr Pepper. Early in the evening, the vibe is a bit more cocktail-lounge. Later, a line starts to form at the door and things get groovy. Local DJs set up in the booth and the whole place starts dancing. Don't be shy about ordering a classic cocktail; the bar menu is one of the best in the city.
