Hi

I've used Waitrose for both work events and for a picnic at the races last year for my 40th birthday, and as Elsie says it is all delivered in lovely boxed plates - which are also useful for repacking and redistributing left overs!! They even do flower displays and ice sculptures to be really posh.
Much easier than doing it all yourself but cheaper than caterers.
Good luck - hope you all have a lovely day.

Carolyn
