Stumbled upon this while in Takasaki. The gram cafes in Tokyo usually have long queues, especially as they only produce 20 portions of these premium pancakes at 11am, 3pm and 6pm. We arrived at the Takasaki store at 4pm and these were still available (and there was no queue!). Score! Super light and fluffy, though I wish they gave a bit more syrup or other condiments.
