A lot of people I know aren't a big fan of Nak Won, but I actually find it a decent place to eat. Nak Won has been around for a long time and I've been coming here quite some times over the years - even more when the movie theatre was still located at First Markham Place.
When you come in, there are plenty of seats as this is a big restaurant - I never see this place completely empty, and they have large tables too, so it's good for large groups. They now have an all you can eat option as well as an order and dine in option (which I always go for).
I think they have a WIDE selection of banchan when you come here, which is always delicious and great. Whenever I come, I always get the pork bone soup, which comes in a stone pot and a metal bowl for the rice. If you ask if this is a tasty Korean restaurant, it might not be the best in the GTA area, but it's definitely an okay place to visit when you're deciding what you want to eat.
