My new favorite bar in the city is the California Clipper, on the corner of Augusta and California. It looks like a David Lynch movie in there, and their house drink--made with grape soda from the gun--goes by the name Purple Martin. It's grape soda and Malibu coconut rum (both things I usually really don't like), served with a lemon wedge. It works very well. I'm a big fan.
My question to you is: does anyone know what kind of grape soda they're serving up at the Clipper? Or where I could get something with a bit more character than Welch's?
