It's pretty simple: Their beer is amazing and so is the food.
If your into the casual sports bar atmosphere, this is the place for you. It is going to be loud and it is going to be crowded but we've never had bad service here even when the place is packed.
If your not sure what to get, try their pizza, it is simply great. My favorite beer is probably the Epicenter Ale. Very light and refreshing. I'm not an IPA lover but my friends say they have the best selection around.
