Here's something to try if you ever get the opportunity. I was in Hamburg Germany and there was this incredible fish market street I visited. I saw for the first time LIVE Alaskan King Crab in tanks. But I was alone so I didn't get it. I should have but I wasn't going to eat the whole thing myself in one sitting.
Then last year I was in Vancouver for an extended period of time (working on a record) and they put me up in an apartment right across from an Oriental Market that had tons of live seafood tanks. It was amazing! I spent all my per diem on that almost everyday and cooked at the apartment instead of going out. Ate like a KING... and one day they even had KING! Live King Crab. I was staying with the guitar player in the band who didn't cook so he was in for a treat. We got Live Alaskan King Crab. It wasn't cheap! Cost about $25 per pound but they were 5 pounds minimum... but it was totally worth it.
I had a feeling the whole thing would taste so much better - especially the lump crab part which often tastes salted and even sometimes a bit "off" in the frozen ones you get in restaurants (and it's often more expensive in a restaurant!). But live it was just perfect - steamed with just lemon and butter sauce after (which it didn't even need it was so sweet). For a crab lover this is an experience not to miss. Hard to find though.
