Food is good for what it is. The problem is the staff (or maybe management). You're often greeted by an empty hostess stand. Then, the wait staff are nice people, but just not good at their jobs. One night our waiter was aloof and had yet to learn please/thank you/you're welcome. You'd ask for something, he'd stare at you blankly, nod, and walk away. Tonight, the kitchen was out of an ingredient (pickled jalapeño). Instead of notifying my wife, they just dumped on raw jalapeño instead. Of course she noticed and asked the nice waiter what's up. 10 minutes later, with my wife's burger now cold, his answer was "sorry we're out". Again, nice guy in that "too many football concussions" kinda way. We also had to ask the nice football player a couple times for water and he miffed up our check.
The flip side to Flipside is that the interior is quite nice and very comfortable.
