We saw a poster saying "どらやき生キャラメル" (※Dorayaki with Raw caramel) so, we stopped at "Tanaka Sake brewry".
※Dorayaki...Japanese-style confectionery. Small bean paste between Japanese-style pancakes.
"Tanaka Sake Brewry" is located 15 minutes walk from JR Otaru station and it's long-established sake brewry where you can sample and purchase local sake, local wine, bean tea, confectionery made from sake and so on.
We chose Dorayaki with raw caramel cream.
We really enjoyed it :)
