I'd like to call to order this meeting of the Shenzhen branch of Chocoholics Anonymous.
If you like chocolate (and who doesn't?), that's one thing. But if you're addicted: STAY AWAY FROM LITTLEJIM'S.
Littlejim's Chocolate and Fudge are the most addictive I've had. You seriously won't find a better chocolate in China.
We're talking about choice local ingredients (apples, plums, nuts, marshmallows, red wine) dipped in imported chocolate from one of America's oldest chocolatiers.
Littlejim's is on Binhe near Huaqiangbei (inside the A-Best store). It's a little hard to get to, but well worth it.
Unless you're an addict. Then STAY AWAY.
