There are many greasy spoons in the city (though not as many as I'd like), and sometimes it's just the little touch of weirdness that sets one apart from the pack. With the 3 Decker Restaurant, in Greenpoint, it's the name and their odd devotion to the club sandwich. You can order a great many different sandwiches here in the club format—that is, two sets of filling separated by a third slice of bread placed halfway between the bottom and top slices. Strange. And wonderful. It's a gimmick. A simple one, but a good one.
Then, there's that name. Generally, if club sandwiches are called by another name, it's a "double-decker." The sandwich has three slices of bread, yes, but two "decks." If someone did decide to call it by the number of bread slices, they would say "triple-decker." But this diner is called the "3 decker," which is totally strange, in its mild way. And that's what makes the name great.
The place is celebrating 30 years in business just now, so go in and say hi. And have yourself a three-decker tuna salad and sliced egg sandwich.
