Jose check out Fog City Diner:

I would avoid Ghirardelli Square and even Fisherman’s Warf, both unfortunately have lost their charm over the years.
If you weren’t flying home so quickly I might suggest the Stinking Rose if you have never been there, but I won’t. Everything, including the ice cream has garlic in it and I for one would not want to sit next to you on the plane.
I wish I could remember our two favorite Italian restaurants in the area. Our favorite Chinese restaurant is not convenient. I don’t even know if there are any excellent Chinese restaurants left in Chinatown.
