I have been to a number of Buca's across Phoenix. I am a fan of the food and the unique atmosphere. Perfect place to have a party, in fact I had my college graduation party here a few years back and it was a blast. Place was designed for family sized gatherings.
My only gripe is that this place is not really designed for one or two people. In smaller groups the bill seems very high and the portions seem to be a bit lacking, your wallet can take a real beating if you want to have a diverse experience.
Still I give this place a big thumbs up, just make sure you book a party and visit the pope room.
