There's a sports bar in Playa D'en Bossa that I'm sure does a roast every day. Can't mind the name but it's near the Pizza Hut.
I always try to eat things abroad that I wouldn't do at home (even when I go to a restaurant in the UK, I'll try to be adventurous) but at the same time, there at days when all you fancy is pizza or a pie and chips. It's certainly nothing to frown upon. As has been mentioned, there are a lot of people who find it peverse that some go on holiday and spend the days in bed after a night's clubbing.
