A couple of notes...
I'm pretty certain NJ Transit stops at that hotel... if that's the case, the bus is by far the easiest (depending what hour you go in) to get to the city. But check b/c the bus (in most stops) runs once an hour on the way out, up to 130 I believe. The train is an option, but be prepared to pay around $20 cabby each way to get to/from the station. And late night after beers, the bus is a breeze.
Down the hatch is fun.. .but the definition of dive originated there. Its downstairs in a basement with orange lights and semi decent tvs. Having said that, I used to frequent it on sundays b/c of there $22 all you can drink beer and wings from m1-6. (its really 3 pitchers per person, but with some tipping you'll never go through 3).
Really depends what you want to do. I'm not a big fan of the other bars so I'll stay quiet!
