Don't look for any greens at the Upper East Side's annual Czech street festival; the only vegetables you're likely to come across are potatoes (as in pancakes) and cabbage (snuggled up with a kielbasa). Take langoše ($6), a slab of deep-fried dough drizzled with garlic oil, then slathered with ketchup and tartar sauce and covered in grated cheese. (Does ketchup still count as a vegetable?)
