Call it a legal game of chicken. A former employee of a Greenwich restaurant has been sued by his former boss, with the dispute focusing on, among other things, the names of menu items.

Frank Carpenteri owns Garden Catering in Greenwich. Michael Natale used to work there, until he left to open his own Storrs-based eatery, called Wally's Chicken Coop. Now Carpenteri has filed a federal intellectual property suit against his former employee, claiming that the menu items at the Storrs deli are too much like those at Garden Catering.
