Despite a sub-tropical climate, Hong Kong is still rather conservative and most professionals wear suits. Business casual is more acceptable for in-house lawyers though most keep a jacket in the office for outside meetings.
Business cards are essential in Hong Kong, indeed in all of Asia and these are presented using both hands.
Mobile phones and blackberries are ubiquitous and Hong Kong has a well connected 3G network. Usage of mobile phones is not permitted in most private clubs.
Handshaking is the common form of greeting. In Hong Kong the family name comes first, so Wong Man Ying would be addressed as Mr Wong. Most entertaining takes place in restaurants rather than in private homes.
Normal courtesies should be observed when visiting someone's home and a small gift such as chocolates or other perishable is considered polite. During a formal meal a toast is often drunk saying Yum Sing at each course.
There may be up to 12 courses served in a Chinese banquet, and although it is not considered an insult to eat sparingly, a good appetite is always appreciated and it is considered cordial to taste every dish. It is customary to invite the host to a return dinner. Informal wear is acceptable.
Some restaurants and social functions often warrant formal attire. Smoking has recently been banned in all restaurants and bars.
Tipping: Most hotels and restaurants add 10% service charge and an additional 5% gratuity is also expected. Small tips are expected by taxi-drivers, doormen and washroom attendants.
