Recently we went to visit friends in Canberra as the National Multicultural Festival was on. What a great feast!
Food, drinks, music, live shows, a lot of people (which is something rare in Canberrs), traditional products and information about different places around the world. But what really got my attention was a food stand selling something called "Chips on a stick". A curlie cutted potato on a stick. There were two stands of this type and both of them had most of the time a long line of people buying. I was impressed to continuously see kids and adults eating these chips.
And of course, I needed to try it as well as everybody else. Not healthy at all but delicious! You could choose the flavors you wanted on them. I had the pepper & lemon one, and it was really nice.
Simple food but served in a creative way... You don't need to create new things to be successful, a good idea to improve something that already exists is enough to win! :)
