I think as the acceptance of Bitcoins keeps on increasing, we will only see the increase in price.
many establishments will also develop this kind of payment system. Maybe not now i hope it will be very soon to happen this.
Accepting Bitcoin this will be the first restaurant in the world KFC in Canada provides meals for online purchase for a limited time only. If it happened then the demand of bitcoin will be increased much higher as most of the people around the world are their lovers.
