About the same time the Golden Gate Bridge was going up in 1935, The Grotto opened as the first sit-down restaurant on the wharf. The newly-renovated and very stylish resto made history again when the chef invented the crab doughnut. The dumpling-Esque treats are served in a trio, with little slices of fried lemon and drizzled with sweet pepper jelly. You may try not to, but you will eat all three.
