Known for their soup bowl-sized lattes, complete with exquisite milk art, Streamer Coffee Company is a longstanding favourite of many a Tokyo coffee freak (and Instagram food porn aficionado).
Now a minor café empire, they're celebrating their seventh birthday this month by kindly offering a whole range of discounts. These even include free coffee for a day – provided you bring your own mug.
Indeed, their 'Jack of all Cups' promotion means you can bring any type of appropriate cup (or vase, or bucket) to their Shibuya shop between noon and 6pm on Saturday April 22 and have it filled with their signature Streamer Latte (¥570) completely gratis.
Note that they'll need to apply an original Streamer sticker to your vessel, and that if your mug isn't large enough to hold 12oz, they'll pour you an 8oz Small Latte instead.
And if you can't make it to Streamer on Saturday, know that they're continuing the celebrations for a full week by offering a 77 percent discount on the regular Streamer Latte from Sunday April 23 to Friday April 28. Grab your vessel, head to Shibuya, and tag us in your latte snapshot on Instagram if you do.
