I love H & V for breakfast. It is a buffet, but the the food is really good there are so many things to choose from, you cant go wrong. We always have 8:00am ressies and I think that is the time they open. The place is almost empty, so we get great character interaction from JoJo and Little Einstein characters. The waitstaff also put on cute shows with singing (songs from Disney Playhouse) and dancing. Kids get to participate. I have not been for any other meal than breakfast.
For lunch, I usually choose 50's Prime Time. Hey, Im on vacation and a little grease goes nice with vacations! The food is good and the portions are enormous. If you are going to skip a meal, squeeze this place in, you wont be hungry for the rest of the day.
I have been a few times (4 - 5 ??) and only had antics once. Since implementing the dining plan, the place is so busy, they hardly have time for it anymore.
Second choice for lunch would be Brown Derby. Its more my type of food, but the atmosphere is not something you couldnt find outside of Disney.
Ive never stayed at DHS long enough to have dinner there.
Good Luck with whatever you choose. If you dont like it, there is always another meal coming!!
