I like Ohana as much as the next person, but I wouldn't call meat on a stick better food.. Comparably I think they are both pretty even. The luau is a nice experience and people overlook the talent that goes into that show.
I say at least do it once and make up your own mind.
Ohana suffers the same cult phenomena as Le Cellier, neither are "outstanding", but because they both have a faithful following, it is made out to be more than it really is. Like I said, I like Ohana , but it's not something I'd cry about if I couldn't get an ADR...
