Fresh, toothsome bagels have made this kosher deli a veritable institution. Tell the bagel monger your preference of bagel, then choose from a sprawling counter of cream cheeses and other sandwich fillings. For a classic, opt for scallion cream cheese with lox (salmon), capers, tomato and red onion ($14.25). If the weather's fine, turn right into 51st St and lunch in pretty Greenacre Park.
Warning: deli queues can get insanely long on weekends.
