Visited these guys on my birthday last year. And while I think Que Bueno could be a good place to eat, right now it needs Robert Irvine (Restaurant Impossible) to come in and save it. The decor, lighting, ambience, service, and food are all average (or slightly below).
To be fair, there was nothing specific that we didn't like about the place...although, there was nothing specific we liked about it either. It's neither memorable nor terrible.
