>>Was the land well themed,
yes, it was better than SWGE (In my mind.)
>>or was the food any good,
yes!!!!!!!!! One of the better counter-service restaurants (albeit too sophisticated to be called counter-service) in a theme park! If you don't like mushrooms, though, it's probably the worst.
>>and how was Koopas Challenges?
At best, it is family-friendly. At worst, it's for children.
You can't feel the exhilaration that we feel when we play Mario Kart (Video Game). However, as a target guessing game, it is the best quality of any theme park in the world.
