Ok where do we start with this place. I am one that loves to try the little hole in the walls. You know the ones people don’t go to. Because never heard of them. Well let me tell you this!!! This is a MUST!! The mushroom and Swiss burger oh my!! The decor is awesome. So if you want friendly service try this one. You want be disappointed

Stumbled upon this hole in the wall while using the DC fast charge on our way through town. Food was delicious and service was speedy. My husband and I shared Steve’s dog and level 1 chili cheeseburger with fried pickle chips and sweet potato waffle fries. The cheeseburger was so big the patty was larger than the bun. Before we left we decided to try the ice cream. We had a chocolate malt and a sector 7 shake. Definitely recommend.

Cosmic Castle was OUT OF THIS WORLD with 15 of us! 🚀 Food was FAST and SO GOOD – everyone loved it! The staff were super friendly and welcoming, making sure we all had a blast. And the kids,They had a FABULOUS time playing pool and playing arcade games! 😄 Highly recommend Cosmic Castle for a fun group outing!
