We came in for a late dinner (read: 9:00 PM) and the place was still extremely full. Luckily, we didn't have too big a group and were seated after a few minutes. I've only had restaurant ramen maybe three or four times in Canada because I've always felt that if I wanted ramen I could easily just make it at home.
I ordered the Tonkotsu black with thick ramen noodles per a friend's recommendation and felt it was decently satisfying. The broth was rich (though a bit salty for my taste), the noodles were nice and chewy, and the ramen already came with a soft-boiled egg and the choice between bamboo shoots, black fungus or corn so I felt pretty full after only half a bowl. I also had a bite of my friend's karaage which was cooked to perfection, so if you're looking for an appetizer that's the one.
The price was a bit steep for the portion I got (judging from other places I've been Sansotei's portion was a lot smaller for the same price) but otherwise I don't really have any complaints. If I'm in the area, I'd go again.
