George was transported to Maine by People for the Ethical Treatment of Animals, which had beseeched City Crab and Seafood to allow the lobster to go free.
The activist group says the giant lobster may be up to 140 years old, although conventional standards for guessing a lobster's age put it closer to 80.
It had been caught off Newfoundland, Canada, and lived in the restaurant's tank for about 10 days.
