Adult birthday party- full buffet or nibbles?

[sparkleandsleep]

We're planning a birthday party in a hired hall in January for around 50 people.
It starts at 7.30- would you expect a 'proper' buffet, nibbles or no food at all?
The venue will do a basic buffet (sandwiches, sausage rolls etc) for £4 a head or I can bring my own food and I cannot decide if people will really want to eat party food as they'll probably have eaten beforehand or just have crisps, nuts and maybe some dips.
Any thoughts?

Hopeful bump 😊

last time I went to a 'grown up' party in a village hall there was a buffet, with sandwiches, sausage rolls, chicken drumstick, pizza etc and crisps and salad. that was DMIL's 70th

I'd rather have nibbles but plenty of alcohol

Good quality pizzas? Can't go far wrong

What's the age though 40th somewhat different to an 80th

It's a 40th
