Beijing restaurant Obentos to sell KeepCups and offer 50% BYO cup coffee discount

Obentos, a Beijing-based bento restaurant, has started selling cups by KeepCups, an Australian reusable cups brand.
The cups cost RMB 200 (approx EUR 25/USD 30), and come with a free coffee upon purchase, and then 50% off on all future takeaway coffees (a very generous and behavior-changing discount that by the way applies to all customers bringing any reusable cup). More at thebeijinger.
