I disagree with a lot of the reviews on here... Just to be clear I went to this exact location on Bloor.
Food: Meh. Not that great. I had higher hopes. I had the Tonkotsu and nothing about it was super delicious. The noodles were okay but it didn't taste that different from my Shin Ramen... The soup was tasted good, but it tasted like MSG. The pork slices were okay, nothing special for a person coming from a Chinese background, and there were only 3 pieces. And there was a LOT of vegetable condiments, which were only bean sprouts and shredded green onion. The portion size was also quite small for the price that it was. The presentation of the ramen was very nice though.
Price: It was pretty expensive! Basically I got the Tonkotsu ramen and a cup of tea (which was $1 btw) and I paid $14 including tax and tips. For what it was, I would have felt better if it was around the $10 range.
Service: I thought was so-so. Could've been better but it wasn't horrible. It took a pretty long time to get their attention when we wanted to order and when we wanted the bill.
Ambiance: I really like the interior of this store. Very modern and everything was cool toned which was relaxing.
Overall: It was so-so. Everything was just "okay". Nothing spectacular at all. For what it is, taking the food and the price into consideration, I would not visit Kenzo again. I'd rather try something new for $14!
