I think I took my first restaurant business card from Cherubino in Kraków. And it was also my first favourite restaurant.
Then whenever I found a place which surprised me in any way (usually of course it would just be extraordinary food) I would collect their card and keep it in my wallet.
Well, you should see the size of my wallet now.
I was recently convinced to keep some of my collection in a safer place (I think a shoe box is good enough) but I still have my favourite cards with me all the time.
Time to share some of my knowledge with you now!
