DoubleTree by Hilton Hotel New York City Chelsea 
Oyster
Star Service
Oyster "It's notable for its full-service restaurant and bar (which many comparable chains lack) and is convenient (if not particularly attractive) location in northern Chelsea near Penn Station and the Empire State Building"
Star Service "In back, Chenton's serves all meals in a standard cafe vein, with a pleasant atrium section and a bar that pours spirits, beer and wine after 5 pm"
