Emeril's is good, but expensive. I found Mythos a little bit better and the prices are a lot cheaper. Emeril's does have a different flavor and I would go to dinner there, like when The Second Cook has his big marriage ceremony there. After all, I have $250 million to spend on something.
In IOA we've enjoyed Confisco's (wish they'd bring back the character lunch), Thundering falls Terrace and Mythos. Enchanted Oak Tavern was ok (dry turkey, but sides were vg) and Green Eggs and Ham had good breakfast sandwhiches but it comes with fries (yuck at 10am).
Nothing I've had in Universal studios was anything to write about.
No-one's mentioned the Hard Rock Cafe - just got back last week - out of all the restaurants - this one was the best on atmosphere and the food was delicious too. Everynight they'd play YMCA and all the Bar Staff /waiters would jump up on the bar and do the actions and everyone would join in - the kids loved it. The easy way to it is to walk to the back of Nickleodeon Studios and you cut through a side entrance and you're there.
Went in Finnigans a couple of times - thought the service & food was great too but was always quite "dead" in the restaurant part.
