Funny that you mention that, I actually have a little tradition where I buy a pizza with Bitcoin on that day.
I've been able to order food online with Bitcoin for a couple of years now (takeaway.com).
I always thought that it would be fun if other people started doing that as well, also to give some support to local businesses that accept Bitcoin.
Thanks for sharing this website with us. Service is not available in my country, but it is in neighbouring country so I will definitely use this next time I travel.
By the way, you can find many Bitcoin Pizza Day events on Facebook, maybe there's even one in your country.
