Not only can you depend on a wide array of delicious pizza, but often times the specials are even better. I've never been disappointed with anything I've had. The wait time is liable to be a little on the long side, especially if you have a larger party, due to the small size of the restaurant, but it's worth the wait.
I wouldn't have expected a pizza place to have the draught beer selection they do, but I'm always pleasantly surprised by their unique offerings. More often than not, they have a special cask ale release from nearby breweries like Flying Dog and Lost Rhino, as well as other lesser known offerings from all reaches of the world.
I could eat at Fireworks every day, and be the happiest 350 lb guy in Leesburg.

We really enjoy the pizza from Fireworks. The only problem is that many people do too and it is generally pretty crowded! The summer is a bit easier when the outdoor seating is available. You can expect quality, fresh pizza with lots of options at a reasonable price. Service is ok.

Highly recommend as a must visit stop. They have a blue cheese and balsamic vinagrette topped pizza that is superb.

Aside from the ordinary pizza toppings they offer an eclectic range of meat, herbs and cheeses.
Good to great crust-If you want a very good pizza give em a try.
