Fast food is not good, but the restaurants are ideal in a lot of ways. I go there by myself and I can sit on their plastic seats with a coffee for almost 19 minutes and watch the world go by. It's difficult to do this in any other social place such as pubs, and other more upmarket restaurants without feeling a bit out of place. Nobody's bothers you, apart from the boy or girl that hands out balloons and even if you ate 140 burgers, one at a time, they would serve you with the same smile and prepared phrases each time.
