When they first came out they were brilliant, easy eating out, varsity of tasty enough food, the fun of going to the salad bar ( as a child) the sources ( which I loved).
I went to one a few years ago and it was beyond neglected, food took hours, cold, rubbish, swamped with dirty plates all round us, and a few others have awful reps round us.
Thinking of cheap, easy place to take DC, they also used to do early bird which was brilliant.
There is nothing now is there!
