Stopped into Koyoi while on a business trip in Toronto and was very pleased. Overall, the atmosphere there is great and is very much like a little diner you would find in Japan. I sat at the small bar and conversed back in forth with the staff while drinking a "nama beeru". I was there on a Wednesday and their special was Tonkatsu Ramen. Although it didn't match up with what I have had in Japan before, it was tasty. The other great part was Koyoi had oden, of which I tried and loved the daikon. Great place!
