Lemon Tree Gourmet Deli is a 24-hour deli in New York that sells sandwiches and cold carbonated drinks. Its signature items are the Chopped Cheese and the Sosa sandwich, and the cheese and mayonnaise can be changed to order. Orders are built by choosing fillings, as with a ham-and-cheese roll sandwich, and the interior is tidy. The amount charged can exceed the posted price, so the bill is worth checking.
