Sansotei Markham is in the Whole Foods plaza on Birchmount and 7. There is plenty of parking. We went in on a Wednesday at 1 and there was quite a bit of space. No wait. There was a constant stream of people coming in though so I can't even begin to imagine what this place is like on weekends.
Service was friendly and efficient - we got what we ordered very quickly after we ordered it so no waiting and getting hangry.
Got the miso black which has garlic oil - the flavor is very strong which I enjoy but some may not. The broth is quite salty but acceptable - the ramen I got with garlic oil at Kiu was even saltier if you can imagine that. It is also saltier than the regular tonkatsu broth I think. I like the thick noodles best! They have a spring to it when you bite and it's nice. The pork they give you is also quite fatty and soft. Softer than Kiu(Ramen Isshin?).
It's a simple meal but satisfying. Their chicken karaage is ok - I think Kiu' s is better actually and kinton. Tonkatsu is the cheapest thing, miso black is the most expensive at around 12 dollars - still not too expensive as far as meals go!
