I am happy that Bitcoin confidently develops and more and more restaurants and shops accept BTC. But if some restaurant does not accept BTC directly, I can use my Bitcoin visa card, so technically I can pay with Bitcoin everywhere 
Bitcoin is one of the best options for the people who want to spend on food and clothes, but bitcoin is one of the volatile currency, so we have to save it for future growth instead of using it now. It's better to use fiat currency in restaurants and for clothes buying.
