Tsukiji Gindaco "Gindaco Festival"
I'll do it this year too! Gindaco Festival

At each Tsukiji Gindaco store, the "Gindaco Festival" will be held for 3 days from August 1st to 3rd (excluding some stores), where "8 pieces of takoyaki (sauce)" will be discounted by "100 yen".

This is a "100 yen discount" for 450 yen for 8 pieces of takoyaki (sauce) with a regular price of 550 yen (tax included, same below) for the period of August 1, 2 and 3. Takoyaki (source) is a "signboard takoyaki" that represents Gindaco. The skin is crispy, the inside is sloppy, and the octopus has a crispy texture.
