Rush Inn definitely has the dive bar look, however it does not function as a dive bar, much nicer than one! Food was good. Average portion but the burger I had tasted great. There's an okay beer selection, not much for draft but a bit more in can/bottle. I got turned on to the Old Chub beer recently (I RECOMMEND) so I had to get in on that action.
Above all else, the service was 5 star! The hostess was very nice and addressed myself and my friend the second we came in. Our waiter was equally if not even nicer. Gave recommendations, had no miscommunication, he was just a positive person and a great waiter.
Overall: I'll go again, in a heartbeat. If I could give a 4.5 I would.
