Over the past year, Toronto’s ramen scene has been steaming hot (both literally and figuratively). And now one of the leaders of the pack is set to expand. Sansotei Ramen, which opened on Dundas a little over a year ago, announced an upcoming location on its Facebook page earlier this week. The new Sansotei is expected to open this winter at 650 Yonge St., just south of Bloor.
