We tried this last October and it was the the one place we really did not care for on our trip. DH and I both had the Veal Osso Bucco, which I usually LOVE, but it was not very good at all (I notice it's no longer on the menu). Can't remember what the kids had, but they weren't thrilled with this one either.
Having said that, we want to do the Fantasmic package on our next trip, so we're trying it again. Hollywood & Vine doesn't appeal to us at all and we won't use 2 credits (we're on the dining plan) for The Brown Derby, so it's our only option left. I do realize that restaurants are often hit and miss and we're more than willing to give it another shot. Can't wait to try something new.
Give it a try. You could love it!
