It is all a matter of taste but we are just back from a stay at the Boardwalk and can tell you that we were really disappointed in the Flying Fish.
I had the steak which was pretty good but would not say it is anything better than the NY strip at Le Cellier. Anna had the salmon and didnt really enjoy it.
As for dessert, I had the trio of Sorbet and I have never had a worse dessert that on property. Only Chef Mickeys prepares food to such a low standard. The citrus sorbet was rancid and acidic, the White Tea and Mint tasted of nothing and the Pinapple and Lime Sorbet tasted ok, but tasted nothing like lime or pineapple. Anna had the Banana Napolean, which she said wasn't very good, explaining that the one at the Yachtsman Steakhouse was far superior.
I definately want to try Jiko as well, as the Filet looks great, and it may be a good idea for our next visit to WDW!
