In the Gaslamp, I would recommend Osteria Pane Vino for Italian, Chive for upscale, Blue Point for seafood, Candelas for excellent authentic Mexican, and Taka for Sushi. The Field is also a great Irish pub with tasty pub food. Also, Hillcrest is a short cab ride away with some great restaurants. Laurel is upscale, Hash House A Go Go has wondeful food, and Cafe W for tapas-style food.
