I agree that Blue Bayou is dark and can get very crowded. It's also very expensive.
In spite of all this, for me,no trip to Disneyland is complete without a waterside table at Blue Bayou with a Monte Cristo.
The restaurant is inside of PoC at Disneyland for crying out loud. Because of that I'm willing to cut it some slack.
I would judge by the standard that I believe Kevin mentioned before. Could this restaurant stand alone outside a theme park?
I don't think it could. My daughter had the Monte Cristo and enjoyed it but my meal was totally bland. CM's weren't very nice either.
The atmosphere was great but that is all it has going for it.
