We took two dining-intensive trips in late 2011 and earlier this year, and I think the only restaurant I was disappointed with was Teppan Edo. None of the restaurants we ate at had truly terrible food, and we never got sick, but I just wasn't happy with TE.
First, we were just two people, and we got seated with two families who were part of an even larger group that occupied many of the tables in the dining room. So, I guess that already made things a bit awkward, since we were left out of the conversations. Second, we saw the "show" at a nearby table when they had their dinner, and it was the exact same thing at our table, so there wasn't much variety in what the chefs did. Third, the chefs seemed to really be there for the kids, and everything they did was oriented towards the kids at our table (who seemed totally disinterested, mainly because they too had already seen everything at the other table). Finally, the food itself wasn't that great. They use a lot of oil to cook on the grill, and everything was oily. DH thought it was pretty good, but I wasn't impressed. I was glad we were on the
DDP, since at least I didn't feel the burn of paying the high prices. Oh, and the dessert selection is between 2 items...we had one of each, and neither was very good.
I guess we could've been worse off in terms of dining, but looking back that is the only place where I actually regret wasting an ADR.
On our second trip, we didn't have a great CA Grill experience (so-so food, so-so waiter, and a storm that prevented any fireworks viewing), but I would be willing to give it another shot.
