#XMRBazaar is very good. But, XMR is a long, long, long way from being accepted at your favorite restaurant.
Square is in the lead for any sort of crypto merchant adoption, and they are #BTC only. Worse, they are #Lightning only. Even worse is the complicity with KYC & custody.
Square is very convenient and offers many options for merchants to accept Bitcoin and Fiat, with their selling point being no tx fees (introductory). With all of these Cadillac features, there is still limited adoption by merchants.
The biggest obstacles with crypto acceptance are: volatility, complexity & convertability. Most business owners have their hands full just running the business, and accepting crypto will not increase their profits nearly enough to dedicate the time to making it work.
It's easier, for those with an interest, to accept fiat, then convert to crypto.
