I went to a wedding recently and the food was brought to the table on one large platter for sharing.
The set up:
At our table we had me, DH, sister and BIL. Then 4 friends of the bride who we didn't know (2 women 2 men) - just in case you think appetite might be an issue. We were all approx 28 to 38 yr old. Wedding was in the UK but from a different part to us.
Dinner:
It was handed to 'our side' first between us we took about 1/4 of the plate and passed it. To let everyone get some dinner then put the rest back in the middle to share - there was nothing left to put back in the middle.
Similar issue with the wine. I wouldn't have expected that to be 'even' DH + BIL don't drink wine and I was pregnant. 4 bottles of wine in total on the table my sister got one glass and when asked them to pass it down for a top up they said sorry empty.
In general they were lovely lovely people easy to talk to and very friendly
