How it (generally) works now: intermediaries pay the restaurant in fiat the equivalent price in BTC on the time/day of the transaction. They facilitate the trade without the restaurant needing to worry about price fluctuations or digital currency exchanges.

How it may work in the future: Off-blockchain processing solutions like the Lightning network (1) have been proposed to decentralize some degree of transactions.

However, this inevitably takes some of the power away from the miners/those who make money off every transaction fee. This has in essence been the struggle/division behind many of the most recent forks or proposed forks; a tradeoff between scale and economics for those that are generating coins or facilitating transactions.

The Bitcoin drama is far from over, and for it to be anything other than (primarily) a store of value in the longer term will require significant technical changes. In fact, at this point, no existing cryptocurrency can support the scale of, say, VISA. It's early days and the race to solve this problem (or fail) is a fascinating drama to watch.
