have you looked at a guide book to see what you might be interested in?

You will wany to get Hong Kong dollars at the airport. I generally use the ATMs there.

What to do and where to eat - there are endless possibilities. You will want to ride the Star ferry to Hong Kong Island. If the weather is clear, you may want to ride the tram to the Peak.

Look for posts by Cicerone who has made extensive posts about things to do in Hong Kong, as well as a very long restaurant post. Use the advanced serch finction at the top of the page.

If you really mean the cheapest way to get from the airport to YMCA Salisbury, this has to be it:

E32 bus (HK$10.8) to Cheung On Bus Terminal, then switch to bus 41A (HK$7.1). Total $17.9. Only one switch, fairly frequent bus, and almost no walk. Of course, it'll take you about 1.5 hours, vs 50 minutes if you take the more expensive A21 ($33) bus which goes direct.

Thanks. I've been researching Bali and had not really planned on Hong Kong, so I came here first. I never do anything without this forum. Any particular restaurant, we must go to?

As for food...what type of food? Most people, if they had a day in Hong Kong, would go for Dim Sum. Everyone likes Din Tai Fung - there are two branches, one in TST in the Silvercord (behind the Langham) and one in Causeway Bay in the Regal Hotel. Not the traditional experience with carts that you would have at Maxim's City Hall, but the food is much better in my opinion. Also "Dim Sum" on Sing Woo Road in Happy Valley is quite good.

Ding Tai Fung is from Taiwan and its main dishes are Shanghaiese. Not local Cantonese dim sum.

No, Din Tai Fung is definitely not local Cantonese dim sum (the poster didn't specify wanting the real thing). But it is reliable and tasty, has English menus, and tourists seem to like it.

For a more authentic Hong Kong experience, have a milk tea and condensed milk toast or french toast (with peanut butter inside) at one of many HK cafes. These are easy to find in Wanchai and Kowloon. They have interesting British/Chinese fusion food unique to Hong Kong. Tsui Wah is one local chain. Or go to Gage street in Central where there are some out door food stalls with tables where you can get real fishball noodle soup, etc.

For a Dim Sum restaurant which is easy to find and with a large selection and English menu = "Zen" restaurant inside Pacific Place mall.

For dinner, and for Cantonese food, I like Lei Garden restaurant.

I use this site often to search for information on eating places.

IMHO there's lots of good Cantonese dim sum restaurants which offer a better dining experience.

I would also recommend trying the roast goose and/or sucking pig.
