Also when in Honkers,try and get across to Lamma Island for the fantastic seafood.You can get a ferry from Central for a few dollars,or if you want to try something different,get the bus to Aberdeen and get a sampan for about $HK200(up to 4 people).This is a one way trip(get the ferry back)but is a great experience.I used to live in HK,and any visitors who came up always raved about the sampan trip to Lamma IS.All the sampans line up together for trips around Aberdeen harbour,so it is fairly easy to find.And a great bit of advice to not get ripped off on tourist prices,is to tell the sampan operaters that you are a new Hong Kong resident.Works everytime.
As for tailors,my personal tailor is Nelson Lin from The New Shanghai Custom Tailor Company.He is located on the first floor (second floor to Americans - That means go up one flight of stairs from street level), suite #126 of the Far East Mansion across Middle Road from the Sheraton Hotel in Tsim Sha Tsui, Kowloon, Hong Kong. There's another tailor named Nelson across the hall so be careful which shop you go to. He and his wife are very friendly,and will even take you out for lunch and dinner a few times.He is so good that a few of my friends in Australia still get suits made and he just sends them out by post.And if you tell him that you heard about him from a guy on the internet who knows Norma from Australia,he will probably give you a great discount,as Norma from Sydney is one of his best customers.
Other things you should do,is get the Number 6 bus to Stanley Markets and try and sit upstairs in the front right side seat.If you survive that,then you never worry about the Middle East again.Stanley Markets is pretty well much a tourist trap these days,but still worth a look.Also you have got to see the Jumbo Floating Restaurant at Aberdeen.Well worth a look at night time only,but beware the food is ordinary and a bit overpriced.And I am guessing that you are a Brit,but for some of the cheapest and best curries in HK,go the ChungKing Mansions on Nathan Rd,and walk up to the 3rd floor.These are some of the tastiest curries I have ever had,and that includes India.It looks a bit dodgy,but rest assured,the food is great.It is on the same side of the road as the Sheraton,and about 2 mins walk.
As for the night life,all the other posts have covered them enough.
I hope you have a great time.And have a Carlsberg for me.
Cheers.
