Thanks to some bad timing, I managed to land myself a flight arriving in EWR tomorrow evening at 9pm, and don't take off again until 7:30am. I've considered going to an airport hotel, but given the time zone changes I won't be able to fall sleep until 1am, and would have to probably wake up at 4:30-5am to get back into security in time (international flight).

The presidents clubs close at 9pm and 11pm, and don't open again until 5am. I'm content to just stay up all night on my laptop until I board my next flight, and get my sleep then, but I don't know about sitting at the gate for 9 hours. Are there any restaurants or bars open late?

I fly a lot of overnight flights and it's frustrating how the airport can be so busy in the middle of the night yet nothing is open.
