Hello! I rarely order cakes as I'm not really a cake person but we're having a big party this weekend and a friend (who makes cakes for a living) has offered to make and bring the birthday cake. I said I'd only accept if she would let me pay her the going rate. She's refusing at the moment but I feel really bad as it's the weekend before Christmas and she's busy enough as it is. So I would like to pay her but have no idea what the going rate for a cake is - it's to feed approx. 50-60 people. We're in London if that makes a difference. Thanks for any help!
