This is an awesome Korean restaurant for noodles and hot pot. It's located in a strip mall off Yonge Street. The interior is sleek and no-frills - not a great ambiance for date night, but it works for a casual dinner out. The staff is all super friendly. They explained the dishes to us and taught us how to operate the hot pot.
We shared the soondae jeongol, a slightly spicy hot pot dish with Korean sausage and other pig organs. It was delicious and super filling. Like most Korean restaurants, you get banchan (assorted side dishes, such as kimchi) with your meal. We liked some and disliked others, but they were all still fun to sample. We also ordered the jjinmandu (steamed dumplings) as an appetizer, thinking we'd eat them while we waited. But our hot pot actually came out first, and we didn't end up needing the extra food. So although they were also tasty, I'd recommend against the appetizers, unless you're extremely hungry.
This was overall a fun experience and a great meal. If you're craving some Korean food, stop by Cho Sun Ok for an authentic and enjoyable time.
