More Get Smart than James Bond, the commercial outlet of the "No. 1 Police Research Unit" is a bizarre example of socialist marketization. Aside from a range of authentic Chinese police gear -- bulletproof vests, sturdy boots -- there's a full range of dated surveillance equipment, including nifty spy pens. Suspicious (often with good reason) wives are said to be their main clients. Open daily 9am to 5:30pm.
