Even with meat-based venues it depends. I went to a 1-star steak restaurant and we asked what they would do if someone asked for a vegan menu. They absolutely do accommodate it as long as they know in advance.
Though to be fair it's a bit different than your average steakhouse
It actually took me until the "that reminds me of the good times". At first I thought it'd be just another rant at our digitalisation so I didn't make the connection.
