maomao,
the weather there now should be still ok, not very cold la, even when i went in dec last time, can walk around in the day with short sleeved tshirts. check the net for the weather report. quite 'zun'
ya no bf, but for mi im fine coz i wana eat their local brekkie there, very nice, thk should be no prob if u staying around the yaumatei area coz they usually got lots of eateries around, 24 hrs! try the wanton noodles, beef noodles(if u eat beef), dessert shops like tauhuay, guilingao and all those mango ice stuff. yum! i go there is to gain weight again. lol
best if u can manage to fit in shen zhen, coz the stuff in hk from there at cheaper prices. if not, go to the out lying areas like sham sui po etc their stuff cheaper.
even the 'gui lin gao' shops price range oso depend on location. TST the price is the highest!
