Orchestrated '50s mayhem recalls the diner in the old television series "Happy Days." Ed's is jam-packed with action: period decor and memorabilia, deejays spinning gems from the '50s-'70s ("Tutti Frutti," "The Twist") and gum-cracking waitstaff, who shtick it up by dishing out rude comments to all -- don't worry; the sass is all in good fun and part of the joint's appeal . The ""Route 66" is available for private parties of up to 35 people, the "Elvis Room" handles groups of up to 40. The bustling corps of valet parkers outside are an amusement in itself. Ed's is one of the city's best bets for visiting families.
