At my local Migros, it's 9.90 francs for a whole roast chicken. Looking at the price of frozen chicken in the same supermarket, 9.90 is a bargain.
And IMO, its very good. I've had much worse in pricey restaurants. A nice crusty bread, fresh salad, good french dressing to go with, very nice. 4 adults ate ourselves full on one of those 'tiny' chickens. And trust me, I can eat.
But do not buy the chicken in quarters, it works out more expensive. Buy either half or whole.
I also took away a pork rib, now that was bloody good too! Very good. Try it out.
Happy Eating.
