Recently, KFC Canada has accepted Bitcoin payments for a short period of time. However, Bitcoin can only be used to place orders online, and only to purchase a new item called "Bitcoin Bucket". And all this special deal will be handled by Bitpay, a fairly common Bitcoin trading tool. Its really interesting news, I wish that I can also buy chicken with Bitcoin in my coutry. 
Major (9 Billion USD) payment provider Stripe has just announced today they stop supporting Bitcoin payments - they conclude it because fewer and fewer are using it, and at the same time fees and transaction times makes it useless as a means of payment. You can see the details on their own website: https://stripe.com/blog/ending-bitcoin-support
From what I have heard, the real reason was not the lack of users, but the high transaction fee. The fee hit a high of BTC0.001 to BTC0.002 ($20 to $40) per transaction in December 2017, and a lot of merchants and stores stopped accepting BTC after this.
