Not familiar with Uber Eats, so I can't provide a correct answer on that one.

I believe if you sign up as a cyclist, they don't check your driving record.

I do it on a bicycle sometimes (so that slashes the gas/maintenance costs). I can make about $70-100 a day, maybe $200 on a good day.

Not worth quitting your job for, but it's something to do if you got time to kill.

Then again, I'm in Hudson County, not the suburbs

Be safe out there.

With great power comes great responsibility.

If it's international, I wouldn't stray too far from the airport and since you said "Saturday" night, I don't think some places may be open that late.

You could check out a bar in the Ironbound or Elizabeth, or maybe see if there's a 24 hour diner nearby for a quick bite (There's Andro's on Ferry and Merchant)

What time are your flights, and are they domestic or international?

I think it's because Journal Square is a busy transportation hub with a busy shopping district and a local college nearby, so expect some hustle and bustle where politeness is left at the door.

2.5 international layover?

I'd stay in the terminal and take up plane spotting.
