The name "bitcoin café" I guess means the whole cryptocurrency world that use blockchain. They are accepting any cryptocurrency, thinking that not all of the people have bitcoin, some of them have Ethereum, Ripple, Litecoin, and so on. The problem is some coins requires more time to be sent, like Ethereum in bitcoin, maybe 10-15 minutes depending on how much transaction fee you used.
Here is the thread where they are discussing about virtual currency eventually becoming a mainstream way of processing retail payments.
