Bottom-line : The food tastes great. I live a stone's throw away from Kothur and have already made it my local for Indian food. I took my family here on a few occasions and they loved the food as well. I have lived in South India for over 25 year and I can vouch for the authenticity of the food that is made at Kothur.
They have great staff who are friendly and courteous. The service speed is acceptable.
If their name board was more visible they could capitalize their Yonge street location better.
