FWIW, we enjoy H&V. We have had B, L & D there. However, my expectations have been low based on reviews. It's a character buffet in WDW. However, we have been very pleased with the selections & leave full. You are going for the experience not the food, per se, like @ V&A, Le Cellier, etc.
H&V is the only place to meet Doc McStuffins. So that is another reason we go. Sofia, Jake & Handy Manny are there too. I believe this is the only place to see Handy Manny now too. Sofia now meets where he used to meet (Animation Courtyard). About every 20min they invite kids to the middle of the restaurant to sing & dance with all of the characters.
Depending on the time you are seated, you should get B & L options. This happened to us on our trip last year (10:15am ADR). This past June our ADR was for 9:15am, so only B options. Also, show up 15-20min early for ADR. This might help with being seated in time for B options. We have not experienced any delays in getting seated here.
