Nuri Village is what I would consider a 'safe' pick for some good Korean food in Mississauga.
We went with their two classic dishes in their dolsot bibimbap and their spicy bulgogi and enjoyed both. The spicy beef bolgogi contained a good amount of meat and various veggies, and the flavoring was wonderfully sweet and spicy. I really appreciated the veggies here and there was a good variety here; there was plenty of bell peppers, broccoli and I was pleasantly surprised to find wood-ear fungus here! The bibimbap was more ordinary but still pretty decent; but I felt like there could have been more toppings as the mixture was predominantly rice.
The banchan side dishes were fairly standard and they only gave four varieties: bean sprouts, kimchi, fishcakes, and the seaweed. They did give a fair amount of them but nothing stood out and I hoped for some more variety. My partner lauded them for their kimchi and thought it was tasty.
The service here was stellar, they came to us twice before we actually ordered and the food and banchan came to our table lightning quick - it's as if they already knew what we were going to order beforehand! The waitress there was also attentive and refilled tea without being asked to do so.
