I know that this is probably not the most appropriate area to post this topic, but it will hopefully produce some good help.
I was invited by a co-worker to a dinner on Saturday night where he is hosting two business clients from a company in Japan. He requested that I go because he knows I have been studying Japanese and can help to loosen the atmosphere.
Could anyone give me suggestions on mannerisms, etc. that I should use during the meal, for example, should I speak in Japanese when possible, or should I only speak in English. Also, should I bring a small gift for them? Of course, I can introduce myself and I am familiar with basic dinner etiquette (such as saying itadakimasu before dinner and domo gochisousamadeshita after dinner), but any other help would be appreciated. ps. sorry for the romaji, I am using a public computer right now so I don't have Microsoft IME installed.
Thanks in advance for all of your help and advice.
