Returning to SD after 6 or 7 years for a conference. Used to live in LA and visited SD often. We'll be staying at Humphrey's Half Moon Inn. Will have car. We have done a lot of SD already, so am looking for a couple of places near the hotel. Nothing too fancy, good food at medium prices (around $20 or so). One place we have never been is the Gaslamp area. We are not club or bar people, so what's good in that area?
