Double Daughters offers great pizza, a great happy hour from 5-8 and a smoke-free environment all in a dark, black and red themed style that welcomes most anyone except for obnoxious, loud frat and sports-bar types. Finally a place I feel at home at.
The happy hour is $2.50 beers on tap and half price wells (around $2) as well as half price martinis (around $3.50). Their martinis are great, too. I would highly suggest the White Rabbit martini. Its blood orange and chocolate, but is very light. Its no longer on the menu, but I still order it.
Also, they host some DIY artsy type get togethers.
