In short, we have a self contained flat. Breakfast is now provided to them upstairs by means of milk in fridge, cereal, porridge and a few essentials eg salt, pepper, olive oil, balsamic vinegar, ketchup, mayonaise etc. However, we have been doing igloo evenings in the garden that consist of a basic hot meal in a slow cooker as the igloo has a fridge and heater as well. They are allowed to use it between 6pm and 10pm every third evening. Normally, we give them a bottle of wine (asking them their preference with white or red). Now we are confident and I have food hygiene qualifications, we would like to charge the evening out at eg £35 including wine and desert. Can this be priced as an 'extra'? We have also done special birthday evenings. We have asked guests to state how much money they would spend on the evening but none wish to commit to an amount as they are repeat business clients. Only one said she and her boyfriend would expect to pay something like £150 for the evening. We just don't know how to market it separately. Has anyone done this type of thing before?
