Tasti D-Lite in Chelsea (7th Ave.)

New York City's leading purveyor of soft-serve quasi-ice cream (it's kosher, has no artificial sweetners, and comes in more flavors than Baskin-Robbins and Ben & Jerry's combined), the legendary Tasti D-Lite has Chelsea branches at 84 7th Ave. (pictured here, 212-627-0550) and at 220 8th Ave. (212-929-0924). Enjoy a dish of pecan praline fudge, butterscotch mania, carrot cake, fluffernutter fudge, burnt sugar, Samoa cookie, triple berry, or whatever other unusual flavor you're in the mood for, and enjoy the fact that these creamy treats have less than 100 calories per four-ounce serving. A added perk is that these tiny shops have public Internet stations. Tasti D-Lite's big Chelsea competitor is Pinkberry, on 8th Avenue (there's also a Ben & Jerry's at 263 W. 23rd St., if you're aiming for a full-on, high-cal ice cream snack)
