PIC: Conor McGregor pictured in one of Amsterdam's most famous 'coffee shops'
There's nothing at all to suggest he partook of the city's most famous delicacy, however.
Conor McGregor managed to take in a visit to one of Amsterdam's most famous 'coffee shops' on a visit to the Dutch city, and the venue was quick to advertise its famous customer to its followers on Instagram.
In the image, he appears to be deciding between a macchiato, a mocha, a plain old Americano or some other intoxicating blend.
There's no way of knowing if he partook of any of the café's more celebrated and 100% legal delights, however, or that he's aware that the man about to take his order is holding a big box of something that looks very herbal and refreshing.
McGregor himself posted a number of images from his trip.
Hopefully he took in a visit to the Anne Frank museum too. You can't go to Amsterdam without visiting the Anne Frank museum.
