I already knew Sansotei from its location in Ottawa, and really enjoyed it back then. We went there on a Thursday night, a group of 4, around 6-6:30, and waited in line for maybe 20 minutes.
Once inside the restaurant, you are served quite quickly, which I cannot complain about, but the moment you finish your soup, they come by and pick it up and leave the bill, which I understand there is a line-up and they want to serve the next customer, but we felt a bit rushed... this is why I cannot give it a 5.
I love the fact that you can choose between thin or thick noodles (i prefer thick). They do not have a vegetarian option.
