Okay, after seeing those prices let me change my advice.
Buy two tickets to the Actor's Theater Lobster Feast. They're $225 a piece, but it's all you can eat lobsta and booze and it's one hell of a party'! The money goes to the theater and you'll have the opportunity to drop a few grand on silent auction items.
Be warned..I've been the last few years and it's a massacre. I have no idea how they clean those carpets.
Option 2: Buy them for $10-$15 bucks a piece frozen (if they're on special at Fresh Market) at a high end grocery and cook them on the grill. Just did a couple on the Big Green Egg and I was told by my wife that they were the best she's had...and she's a lobster snob. (Of course what else is she going to say?)
The secret is to to slice them open and put a skewer through them and to keep hitting them with butter as they cook. As they cook they puff out giving you that steakhouse look. Hit it with a little paprika or cayenne pepper after they're done for a little color if you're a wild man. Plenty of details and ideas available via Google or you tube.
