We ate dinner at Hollywood & Vine on our trip in April and it was our first time eating there. I had read/heard pretty much nothing but terrible reviews of the place, but - as with everything at WDW - we wanted to try it for ourselves.
This was Minnie's Springtime dinner (not sure how much they change the food offerings as their seasonal theme changes). We all enjoyed the food very much. Our party was two kids, aged 8 & 5, and four adults who all have experienced and enjoy fine dining but also have a realistic expectation for food at a theme park buffet. There were many salads (vegetable, pasta, and grain) as well as roasted vegetables and all were fresh and tasty. The entree options we had (stuffed chicken, pork with some kind of chutney, roasted turkey, a few different kinds of meatballs, among other things) were hot and very good. We all enjoyed the dessert options more than the ones served at the MK Sparkling Dessert party, which we had done the night before. They had the typical kid buffet offerings which my kids enjoyed. We ate at prime dinner time, so it was loud and somewhat chaotic (as to be expected at a character buffet), but our server was attentive whenever we needed more drinks or plates cleared.
The best thing about our dinner was the character interactions. The characters were all dressed in spring outfits and were all very sweet and really interacted well with our girls, giving autographs and photos and involving the adults at the table. We didn't feel rushed even though when the characters passed through the restaurant was packed. We actually enjoyed these non-speaking characters more than most of the face characters that we interacted with during our trip.
We had gone to Chef Mickeys on a trip in Sept 2015 and we enjoyed this food much more than that. We are actually planning to go back for the holiday-themed dinner on our upcoming December trip.
