I was invited to a dinner party this weekend.

I presume it would be customary that I bring something (or am I off base here?)

I have no idea what so ever to bring as a gift. I do not know these people very well either so I have no idea what they like

Any ideas??

I hope this is the right forum to ask this. My other choice was omni but I wanted this to be directed to the Japanese or at least Japan travel audience

thanks
