You can drink at 18 (legal) - In HK they are not really strict about serving alcohol. In most places they don't even check IDS

I would not take children to this place after 8 pm.

Hi. Get a map first. Jump on the Airport Express train and get off at Central and at the MTR Station there will be directions. Its a short walk albeit uphill to the Mid-Levels. If unsure ask at the MTR Kiosk who are always helpful. Enjoy yur stop over. Best wishes. Frank

Hi, I didn't go from the airport. You can catch a cab from the airport or the high speed train to Hong Kong Island and can catch a cap from there

Yes, I agree with others, most likely your recommendation is for Braza Churrascaria Brazilian Steakhouse located at 3/F, Grand Progress Building, No.15-16 Lan Kwai Fong. Walking distance from Central or Admiralty MTR stations or the Conrad / Island Shangri-La across the Park. Personally, not sure why anyone would want to eat Western or LatAm (even good steak) when in SE Asia when so much excellent local food to choose from. Plenty of excellent Dim Sum restaurants around Lan Kwai Fong.

Uber is safest and best after a nightout at LKF!

Ps. Locally it's known as 'The Escalator'. ( Central to Mid Levels escalator is the official name for maps etc) . Hope this helps.
