We had a lobster boil on Sunday. I found this amazing live seafood market, Sun Fat Seafood Market, in the Mission where they had tons of fresh fish, seafood, and lobster.
We went and picked out a two-pounder. (I named him Tony on the way home.) We also got a live sea urchin, some Manila clams, and shrimp.
Sad to say, the uni was not as good as the stuff you get in a restaurant, but definitely interesting to try as a first time, fresh out a sea urchin.
