The Toy and Hobby Museum, Café Mido, Temple Street Night Market, Capital Embroidery, Wu Jue Nong Tea, Cheng Shing Fan Factory, Baraha Jewellery, Nam Cheong Wooden Handicraft, Jade Company, Jade Hawkers' Market, Tin Hau Temple, Café Kubrick, Broadway Cinematheque, Reclamation Street Market, Wholesale Fruit Market
Interesting and fun at any time of the day. Temple Street Night Market opens after 4pm. Café Mido is good for an authentic taste of Hong Kong but if you prefer something more western, Café Kubrick is your best bet.
Just be careful crossing the streets and be aware of your surroundings.
