I've had lobster sashimi at the Tajima on Convoy and it was amazing. Unfortunately, it is a special that I've only seen them offer twice. I even went to the Mercury St. location today for ramen and asked the waitress if they plan on offering again anytime soon and she had no idea what I was talking about. I think she was a little amazed about the raw factor. I was too when I first tried it (is this going to kill me?) but it is well worth it. The lobster is still moving when it gets to your table. Anyway, I was wondering if there are any other good places to get this yummy dish, and would recommend the non-squeamish to definitely give it a try. BTW, look for the ama-ebi at Tajima also when they have it. The shrimp will fight you for their tails back as you grab them off the plate, and fried shrimp heads after. Yum!
