Hi, little advertisement on your local shop window, search web if there is any small business forum for your local area which help introduce small business. in fife we have (small business connection fife) a page on Facebook, where everyone advertise for free about there business. Hope it helps.xx
Social media has been the most effective way of getting the word out about our supper club. I would suggest getting a website first and then joining Twitter and starting a Facebook page. Good Luck!
Get in touch with local radio or newspapers. They are always looking for a story and if you have the first supper club in your area, they will definitely be interested. Search for them and message them on Twitter and facebook also as a way of contacting local media.
Social media like twitter and FB has worked well. Also if find local food blogs promoting other places ask them to add you to their blogroll and give you a shout. Good Luck
