Ellis Island Rocks!!! We always go there. It is kind of a dive, but why pay 15 dollars for a burger at one of the casinos when you can get the exact same one for 6 bucks. Also, they have microbrews for 1.00 and homemade rootbeer.
When we went in November, I used a few restaurant.com certificates I bought 80% off. We usually ate with those for about $20 for both I and my DH. There was a pub downtown that we ate at that was very good using one of these certificates.
