Very good! Despite the fact that it was packed when we arrived, we didn't have to wait very long to get a table. (We waited around 15 minutes, which isn't long for a place like this by my standards - especially on a Saturday evening). What I like about this place is all the decor. Plenty of things to look at while you're waiting. There's even framed pictures on the ceiling. Of course, the best part of the experience is the food! I had the bacon cheeseburger and it was delicious.
The only bad thing was that our server never asked if we wanted more fries. We actually forgot until we walked out of the restaurant asking each other, "Hey, wait a minute, wasn't this place supposed to have 'bottomless fries'?" So I guess it's kind of our fault and maybe they don't give you more fries unless you specifically ask for them.
One thing to keep in mind is that you might have to shout to everyone at the table (and to the servers) since it's pretty noisy in here. It's a very casual dining experience so it's what you would expect, but don't expect to be able to speak in a normal "indoor voice" here.
