People really love that nama caramel:
That's Hanabatake Bokujo (Flower Garden Farm or something like that?) who opened up a couple of stores in Sapporo last month. They're like a dairy farm that specialise in, amongst other things, that coveted commodity 生キャラメル - nama caramel - really soft fresh caramel. It's a bit like British fudge but softer.
And that queue is ALWAYS there.
At both stores, the one at Sapporo Station and the one in Odori, every single time I walk past there's a snaking line and security guards present to enforce it. The stuff is delicious, but I'm astonished at this bottomless appetite for it. I assume this one is also popular for tourists, this is where they would leave for the airport from, but the one in Odori they have to queue outside. This is Sapporo, so as you can imagine it is hardly queueing weather at this time of the year.
I'm sure they sell other stuff too, but I've never been able to get inside to check.
