Time Out says
Any foodie worth their salt should pay a visit to HeyTea during their Shenzhen food crawl. Specialising in hand-shaken beverages, this brand has gained widespread popularity on the Mainland, with people queueing for hours to get a taste. Try the rich cheese-cap tea, special fruit tea or bubble tea – all of which will leave you hankering for more. HeyTea outlets are widespread across Shenzhen but, lacking the usual crowds, the cosy and comfortable ambience of the Upperhills branch is a perfect spot to linger and people-watch.
