I am trying to decide what kind of dinner to have. We would like either a plated dinner or something between a plated dinner and a buffet (I do not wants guests getting up and serving themselves at a buffet). Would it be very strange to have a selection of tapas served to each table? I've been to quite a few tapas restaurants, and I love the idea of having lots of little dishes that are passed around the table. Is this too informal (our wedding will be formal)? Thoughts?
