Just came back from HK yesterday. I've to admit, the food there is DAMN good. Wanton Noodles is just a fraction of it.
I stay near Mong Kok MTR, and any food store is just great. Wanton Mee, Mix Beef Mee, Chey Zai Mee, Teng Zai Porridge ( with You Tui ), Dim Sum... practically anything... and yea, dun miss out the road side fishball stall... damn good, get the spicy ones...
Shopping is another good part of it... basically anything is around 20% cheaper than SG (food also cheaper).
Camera stuff, around Mong Kok MTR got two very well stock stops... they are Wing Sheng and Man Sheng lor, but they are not the cheapest around and they dun bargain with you... bloody hell... got my Gitzo at Man Sheng at a slightly higher price (still much cheaper than SG), and the second day when I Accidentally stumble into Tin Cheung ( in Tung Ying Building Grd Floor, 100 Nathan Rd, Exit B1 from Tsim Sha Tsui MTR ) and found out they are selling for HKD$350 cheaper... ouch... ;( if you are ever going to HK, Highly recommend Tin Cheung.
Subsequently I got some accessories from Tin Cheung, dun have to bother abt bargaining cos the price is already cheap compare to sg, but they gave me some good price when I asked for a reduction...
Tin Cheong have lotsa Leica stuff, and is quite well stock with other canon/nikon stuff as well, lotsa gitzo/manfrotto stuff, bags, some selection of camera straps (get the Domke ones, quite good)... yea, just go there lar, you'll see...
