They are also a nicer option, frankly. The service in Costa is appalling - it feels as if they think they are doing you a favour, not being paid to do a job..................
I also really like Aminas whne in greasy spoon mood - they are always always charming and kind, and the people are warm and interesting. They were great to my Mother, in her wheelchair, when we went in during the summer and they won my custom for that as well as the lovely service.
