I do a lot of fund-raising, my upcoming one is going to be held in the restaurant area of a local bar.
We have a group of people visiting from the UK and a lot of people from here attending too.
I do a fun quiz, just A4 size charging 5€ per person, also a drinks raffle, you need a friendly bar to do this. Make up vouchers for say `£1, £3 and £5 or equivalent to the prices in the bar. then sell raffle tickets, for £1 each, depending on the numbers sold you then call the raffle handing out the vouchers towards the cost of peoples drinks/meals. You hand out as many vouchers as you wish, I usually fine 6to 10 is fine.
It always raises quite a lot for little outlay.
Also a book table, I did a silent auction once and I do a promise auction with a friend at Church, every 2 years.
Good luck.
