V&A is too formal for me - I am sure I would enjoy it, but just not excited about putting on a coat and tie to eat at WDW. Cal Grill is overated in my opinion - the food is great, but all the hullabaloo about being there to see the fireworks detracts from the overall dining experience.
Jiko is my favorite restaurant at WDW. Great and inventive food, a super wine list and wonderful service. The decor is also lovely and being at AKL is always a treat.
At the end of the day, you can't go wrong with any of the restaurants listed as options.
