First time was this past December and we fell in love with the place. In fact, we have an ADR for Cali Grill in October timed out for the fireworks and there's a VERY good chance it'll be getting cancelled because we really want to go back to Citrico's.
It's very much one of the best "secrets" in Disney. You can get an ADR at pretty much any time - the place was probably only 1/3rd full when we went. The meal was the best meal I've ever had at Disney, our waitress was wonderful, and the atmosphere was so relaxing.
