Some people travel all the way to Spumoni Gardens for a slice (where the cheese is underneath the sauce) and refuse to leave Clemente’s before a third bucket of crabs.

We are those people. And we couldn’t wait for Defonte’s lunch hero. (So we got one for breakfast.)

The Red Hook sandwich shop, favored among hard-working appetites since 1922, opens its Gramercy outpost today.

Expect old standbys (Vinnie Barbarino sausage and peppers, potatoes and eggs, caprese with the works) and an expanded menu of salads (tuna with olives, pickled veggies galore). Our arteries tingle with joy for the scratch-made mozzarella and fried eggplant. This is legitimate locavore stuff, people! You’re on a diet? Please stay home.

Fraternize with drop-ins from the old hood (“I’m fourth generation!”). And hang out old-school Brooklyn style once the enclosed porch with sidewalk seating is ready.

Then you’ll really feel like family.

Defonte’s of Brooklyn, 261 Third Avenue, at 21st Street (212-614-1500 or defontesofbrooklyn.com).
