Temple street is located in jordan, where bargains of items start. Try your best to push down the price if you are going to buy more from a stall alone. If you're bargain can't be contained then walk away and maybe 70% of the time they will try to fetch you back for a solution or a final best price,LOL., And also many chinese seafood restaurant could be pricey..give it a try if you're in the area.
Getting here is quite easy depending on where you are situated, if you're on the island line that is "Hong Kong Island" going by "MTR" that is in other countries known as Metro or Transit.
Take the blue line that is "Hong Kong Island" and drop off in either "CENTRAL" and interchange to the Red line that is "Tsuen Wan Line".there should be only one way towards "Jordan" that is only 3 stops away passing
ADMIRALTY then TSIM SHA TSUI AND finally JORDAN, where you will be getting off and you will need to Get to Exit A then when you get to the street face right walk straight and pass 2 blocks and you will be on the street called "Temple Street". Go in this street and walk for roughly 5~8mins and you will pass some professional hair products and also some local snack stalls and you will be in front of the "Temple Street Night Market".on the right you can have their local seafood that I've mentioned earlier..Good Luck
But personally I'll recommend Ladies market which is located in Mongkok area for buying for personal stuff, friends or for souvenirs stuff.. You're choice..
