Ye olde clam house
Veteran franciscans know one of the best places to get the best seafood in the city is. Ye olde clam house on bayshore blvd near 3rd Street and just a stones throw from the alameny off ramp from 101.
Ye olde clam house is a wonderful place to eat but if you're in the city and you don't have a car you could hop a Muni #9 San Bruno and it might take awhile but you'd eventually get there and it's definitely worth it!
