I am arranging a dinner in late August for a friend who is giving a reading at a bookstore in the Castro. The reading is at 7, so dinner will be afterward. It's on a Friday night. I won't know a count until closer to the event, but I'm guessing 10 to 20 people. Unfortunately I don't spend much time in the Castro area, so would really appreciate suggestions for an appropriate restaurant. It should be moderately priced (some of the people don't have a lot of extra money) and a bit buzzy, as I'm sure we will all be high-energy after the reading. Thanks for any help!
