To be honest, the taste highly dependent on if it was lava hot from the oven, vs 1 hour later.
For prior, it worth 4 stars. When it's fresh, it was flaky and molten hot and taste so good.
For latter, it is probably 2 stars max. The crust won't be good. The apricot gel congealed and too thick to match the cheese crepe brûlée center.
I also bought the mini Mont Blanc. It was decent, but won't drive me to think of it and miss it like other stores in Japan.
It's still a good experience to try it out, especially now the line is short.
Also I noted that did not remind the customer of the amount of time it can leave out in room temperature beyond the sticker on the box, not very traditional Japanese cake shop style from customer service perspective.
