We stopped here before heading up to the Space Needle because we'd heard great things about the pizza. The pizza was in fact delicious. We got The Space Capsule pizza and it was a ton of food, but great. The crust was awesome (the best pizza crust in the Gatlinburg area, by far). They also serve Cheesecake Factory cheesecake, which is extremely good.
The Flying Saucer is located inside an arcade, which makes it extremely loud (between the kids running around, game noises, etc). It was so loud that I could barely hear my husband, who was sitting right across the table.
Aside from the noise, the place is great. High-quality pizza at great prices.
