Help with implementing Cryptocurrency payment at a restaurant

[smsm90]

Hello

Im helping a friend figure out the best way to implement Crypto payment at his Restaurants.
I have researched and found a couple of  Payment Gateways Online but most of them only accept BTC, Eth , BTH or they only payout in BTC and USD.

Is there a “simple” way we can accept Cryptocurrencies like OMG, NANO, BAT, Dash, Monero, Verge (JK), etc

The restaurants is Located in Stockholm and Amsterdam

Have you tried CoinPayments? The site says that they support over 400 altcoins, for a fee of course. An alternative way would be to run your own nodes and code everything yourself.
