Honestly, I think the idea of H&V is cute, a vintage diner, but the atmosphere (and the food) at Sci-fi BLOWS H&V out of the water! You will feel so much more satifised if you go to Sci-fi. It's my favorite sit down resturaunt out of allll of the Disney World! :]
If you have any further questions or concerns I'd be more then excited to help you out!
Have a magical day!
