The only fireworks display that Virginia Beach has is on the 4th of July holiday  is the Stars & Stripes Explosion

You can see from that page that they are located all over the oceanfront.

I would recommend staying at Courtyard Marriott South on 25^th Street to get a good viewpoint.  Any balcony that faces the ocean will be able to get a great show.

Regarding restaurant viewpoints… it might be hard to see the fireworks from any restaurant… but most of the hotels have restaurant/patios that you can walk up to.

Ocean House on 19^th Street is a good place to go or if you can get to the top of the Hilton on 31^st Street (Sky Bar) that would be a really great perspective.
