BW Kafe is an unusual-looking cafe in Moscow.

BW Kafe first made international headlines last year, 【小题1】 photos of the St. Petersburg branch became popular online. Designed by Russian artist Anfisa Toshina, the inside part of the cafe looks like a picture 【小题2】 (draw) with charcoal (木炭) on a piece of white paper. It creates the false impression that you are the only 3D “object” in a two-dimensional (二维的) world. It’s a pretty nice trick (戏法), 【小题3】 one that might seem strangely familiar if you 【小题4】 (be) on the Internet sometime in the last two years.

This whole coloring book idea is 【小题5】 (actual) nothing new. It【小题6】 (introduce) in Korea first, by the designers of Cafe Yeonnam-dong 239-20, but has since been copied by other entrepreneurs (创业者) looking to capitalize (利用) on the 【小题7】 (popular) of the design. We saw similar cafes open in Japan a couple 【小题8】 years ago, now Russia, and I believe there are many more all over the world, not to mention official Cafe Yeonnam branches.

While it may look like a copy of Cafe Yeonnam-dong 239-20, it’s a pretty well organized one. And for 【小题9】 (European) who can’t visit the Korean cafe, it’s a chance 【小题10】 (enjoy) a cup of coffee in a 2D world.
