I'm a big fan of Kenzo, it's pretty damn good ramen made by non-Japanese, non-artisan noodle makers.
You can definitely taste the Korean influence in the King of Kings dish.. watch out if you get level 3 (spiciest).. it's not blow-your-head-off but beware (especially if you are a slurper).
I've been to all 3 locations (Annex, Dundas and newest on Yonge) they are consistent. I will continue to go to Kenzo because it's the best I've had downtown (better than Ajisen, Inoodle, Liberty noodle) but that said, I have not been to j-town.
My only criticism would be that the sodium level is high and I do suspect MSG (gotta have a bit but I think there's a bit too much).
Service is mediocre and portions are large.. well worth it.
