I enjoy a nice evening out at a local restaurant, whether just simply to relax, catch up with old friends or even to meet new people.
I will genuinely recommend a place to colleagues and friends if I enjoyed it, and I like to keep track of where I have been and what I thought. I collect Restaurant Business Cards, whether for my own reference or to spread the word. If I am feeling in a generous mood, I will also sign up to their newsletter/mailing list. This has mixed results. Some with spam, others with genuine offers which ensures repeat visits.
Restaurant Business Cards provide a great medium for keeping a quick note/review on a restaurant while keeping the contact details handy (similar to my index card review collection). If possible I like to note down things to remember for my next visit.
I used to keep these tucked in the cover pocket of my Filofax, but I am considering going the restaurant card holder route.
