With a couple of friends, I stopped by Main Event for lunch today. (That link will eventually redirect you to the restaurant/bar's Facebook page, as its website is still under construction.) Griff posted about it back in April, before it opened; there's some help additional information in the comments. Main Event is at 835 Main Street--the old Lava Lounge, next to what used to be Bouchard's (and before that, Burrito Joe's).
The lunch menu was simple, but has some good food. The place offers sandwiches, salads, and freshly made pizza. All three of us opted for a sandwich, and all of us agreed that they were made of fresh ingredients and tasty. Their pulled pork and BBQ beef sandwiches both come on pretzel bread buns. I had a "Wellington"--roast beef, a potato cake, Colby cheese, and some sweet-and-sour sauce served on a Kaiser roll. It was probably the only truly original sandwich (most were clubs or straightforward, single ingredient creations) on the menu, and I'm glad I tried it.
Service was fast and friendly. It's definitely a good spot to hit on the way out of the courthouse (or on a lunch break if you're stuck in/work at the courthouse all day). And the prices are right: my sandwich, chips, and a pop cost $7.50.
Main Event is also open late at night. The bar was clearly well-stocked. The venue features a fairly large dance floor with a DJ booth. Our server ran down each night's theme for us, all of which I promptly forgot (one night is 80's music). But it sounded like it might be worth checking out.
