Had a delicious lunch at Sansotei and had to share my experience. We arrived as a party of 3 at 11:40am on a Friday and only had to wait 5 minutes. As this place is growing in popularity, I would suggest arriving no later than 11:30am to avoid a lineup since they make you wait outside along the sidewalk. We were seated by the door so we felt gusts of cold air every time the waitress went outside to add people to the wait list or to call people into their seats. A double door entrance (with an enclosure) would be helpful in this regard.
We ordered the fried chicken appetizer and the tonkatsu ramen with the recommended thin noodles. The appetizer came with five pieces of chicken and a wedge of lemon. it was fried to perfection and the delicious start to our meal.
The noodles arrived shortly after and were absolutely perfect. The eggs were the best soft-boiled eggs I've ever eaten and the pork (comes with 2 slices) had a beautiful charred surface. The noodles came with a generous portion of wood fungus mushrooms and the soup was not too salty nor too greasy.
Unlike Kinton, the environment is actually conducive to conversation and the seating more comfortable. The service is attentive and polite. My only suggestion is that they serve complimentary hot tea. This seems to be a rarity at downtown Asian restaurants these days but I feel it will complement the food nicely.
Sansotei is winning the Toronto ramen race in my books. Next step, Santouka!
