Best Cafes/Coffee Shops in Shenzhen?

Hi Everyone!

I am currently doing some research on the best and coolest cafe’s or coffee shops in Shenzhen, (besides from Starbucks). 

Cool can be classified by original themes, cool decor, interesting people/staff within, great quality coffee/green tea etc, or maybe the concept is quite new like a Cat Cafe (I heard there’s one in Futian?) or whatever you feel you like about it and please elaborate.

There is very little information on the best cafes around Shenzhen, so if you have great places you’d like to name, it would be much appreciated :-)
