My lobster experiences are memorable too.
First time i was so slow dealing with the shell that it was cold by the time i ate it. Gets kinda rubbery when cold.
Second time the memorable part was being seated with strangers. They got their lobster as we sat down, and we chatted, then new strangers came when we got our lobster, and we chatted.
I'm sure i've eaten lobster at other times, and it was fine, but i guess i don't remember much beyond the butter...
