We are getting married in October and are planning buffet food on the evening. How much buffet food would we need for approximately 26 people (20 adults and 6 children)? Sorry, we’ve never organised a buffet before and the venue have advised that any food left over would need to go in the bin so we don’t want to order too much! Is it a general rule that we cater for 2/3 of the guests or would you not risk it and over cater? TIA
