This is one of two acceptable ramen places near work. The other being Hakata Shoryuken, which I had stopped going to since it felt like they added MSG to their soup base.
When I asked the Kinton staff whether they had used MSG or not they said there wasn't. From my observation, the broth itself does not feel like it had any MSG. The taste from the meat and broth seemed natural. However, the amount of noodles is very small and generally not even close to filling for $10.99 + taxes and tip going to about $14.
Unfortunately, I still got the MSG tingles in my mouth. I am thinking that it may be their preserved egg that would have the MSG component. Egg isn't supposed to be that flavorful. I think started to feel the numbness on my tongue after eating the egg.
I would try it again just to confirm that it is the egg, but because I had the MSG feel I am only giving this place past a 3-star. Though I don't think I would make it go higher as 3-star even when because of the price to quantity ratio and without the egg, it's not a complete ramen for me.
