Nope no Metrolounge, there isn't enough first class traffic at this station to warrent one. Plus Amtrak does not own the station, nor did they build it. The station was built by the city and NY State.
That said however the station is quite nice and does have a comfortable waiting area. There are also a few places to eat and they are supposed to be adding more. The platforms are now highlevel and you no longer need to walk across the tracks, as there is now an enclosed overpass that is still part of the station.
