I have been to this restaurant two times since they opened and the food has been amazing every single time. Big fan of their garlic noodles and chicken tenders. It’s a perfect spot to stop by if you’re in downtown around GSU and the Fulton county buildings. The best part is they’re open late!
Wonderful service, beautiful ambiance, and fantastic drinks! I had the Long Island, and it was one of the best I’ve had. Highly recommend and will definitely be returning.❣️
Such a cute diner! The atmosphere is great, the food is even better! We had the smash burger and literally could not stop eating. Rain was our service and she was so sweet! Definitely need to check this place out if you’re in the area! Can’t wait to come back next time we’re in town.
