I have a friend coming in from out of town and we will only have time for one dinner in SF. This dinner will be on a Saturday night. I would like to go to a place that is fun, good, and unique. I have had exceptional experinces as Farallon in the past and was thinking of taking him there. However, I am open for trying something new. Possibly A 16. Any suggestions of places that won't break the bank but provide a good dining expereince.
