It's not that you can't play chess in cafes (I've also done that), but chess is more complex and is -perceived- to be much more complex and serious.
Backgammon has dice rolls and less complex strategy, so it's nicer to play over coffee and chatting. Rolling doubles also gives potential for comeback swings so it can be fun for spectators too.
