Visited around 6pm on a Thursday evening, and it was pretty empty when we first walked in, progressively getting busier as the night went on. I was a bit worried I wouldn't be able to tolerate the spice of the famous dakgalbee dish, but it wasn't too bad. We were a party of four, so we got two portions of the seafood and chicken versions, topped with their original sauce, mozzarella cheese, and rice cakes. I think the cheese helped tone down the spiciness, so it's a good addition if you have low spice tolerance like me.
The servers were very nice, and didn't seem to mind that we lingered for an hour after our meal, chatting away. Joons is a simple restaurant that I would definitely recommend trying at least once if you are in the North York area.
