Hard Rock was last year. We did it and while the more 'exotic' and specialist meals were not available, the basics all were, and if my sister can find something she likes, then everyone can! We got main meal and drinks free, and then we also had dessert, which we paid out of pocket for!
This year it's supposed to be: Pastamore, Latin Quarter, Pat O'Briens, Bob Marleys and Margaritaville, unless it's changed since the beginning of the year! I should imagine that it will be the same sort of set-up as with Hard Rock. 6-10 different main courses to choose from and then a drink! Who cares when it's free though?!
