Coffee

Compared with other less cosmopolitan Chinese cities, Shanghai thankfully has a large and varied coffee selection that ventures far beyond the standard fare offered at large chains such as Pacific, Costa, Starbucks and Coffee Bean.

Most coffee shops and cafes will offer free wifi for patrons to use, so they make good places to rest, read, or work if you're a freelancer.

For coffee emergencies, the ubiquitous 85C provides potable Americanos and sea salt cream coffee (海燕咖啡 - hǎiyàn kāfēi). CMart convenience stores also have a cheap, non-toxic option available.
