Cafe Fay has been running this little machine between its espresso-maker and sink that lets you print a drinkable picture of yourself, rendered in sort-of-decent resolution. A sipable selfie, if you will. The pinnacle of technological innovation. Earth is now a Kardashev Type III Civilization. Read on to find out how you can put your own selfie in a latte.

It was thought that humanity was only really, really good at two things: adapting the surroundings to suit its needs, and killing itself. In the last two decades (debatably earlier), mankind's third great knack was finally discovered; selfies.
Selfies, am I right? Everyone's an expert. The problem is that no gallery wants to grace the world with your masterpieces. Snobs. Forget them. Print your selfies on the most exalted canvas of all; lattes. Their fleeting nature renders them sublime. 
Backing up. There's a cafe on Changle Lu called Cafe Fay. It's got kind of a travel theme and a drinks list that's longer than your average coffee shop, but the draw is their printer. No ordinary printer, this. This printer uses safe (probably) food dyes to print whatever image you want onto a layer of creamy something floating on top of your favorite tea / coffee shop beverage.
Step 1: Snap a Picture
The shopkeepers can help you out if you don't have your selfie stick with you. It's a circular crop, so stuff on the sides and in the corners will probably get cut out. Plant that beautiful mug of yours right in the middle of the frame.
Step 2: Send the Picture to the Man Who Controls The Box
You can do it via WeChat. He'll crop the image, prep the drink and set up the machine to work.
The Box itself
Step 3: Receive Your Selfie Drink
No retakes.
Optional Step: Make a "Reverser Cam"
Film as you mess your face up with a straw, then reverse it using one of those handy-dandy apps. The owner of the cafe'll help you if you don't understand how it's done. And there, you've ensorcelled your own visage from a vortex of food dyes, Dumbledore.
Step 3: Sip Your Selfie
MMmmmm. Inceptional.
As far as I can tell, it's one of the few (if not the only place) in the city that does this thing. Cafe Fey's been around since like 2012, which is sort of impressive in itself. They won't say where their magical printer box is from, but the owner was quite proud to announce that they beat Korea to the punch.
It'll cost you 23rmb on top of the price of the drink, and it can only be done on the drinks without a red star next to it on the menu. And it can only be either cold or sort of lukewarm, otherwise the colors will start getting all wonky and the cream goes weird.
How does your face taste?
Like a layer of questionable cream cheese. That top layer doesn't taste that great, honestly. I'd stick the straw in and just enjoy the drink underneath. This has the added benefit of letting you watch as your own face contorts and twists into a hideous parody of itself, finally settling into a mushy, discolored mess at the bottom of the cup. A transcendent experience. I recommend it to all.
