Oh no. I've been dying to try Jiko.
Definitely try out Jiko. It regularly makes the "top 5" lists of many, many posters on these boards (including my own). I am sorry that the one poster had a bad experience, but that seems to be more the exception than the rule.
As to the original topic, I have been to just about every resort TS restaurant at least once. The only place that I will not return to is ESPN Club. I have been there on several occasions and it has always been terrible. Over the years, I would keep trying to give it another chance, only to be disappointed again. So after my most recent bad experience (which was over 3 years ago), I decided to never go there again.
