Spilling the Beans at a Coffee Stall

2 brothers in their 70's operate this unpretentious street stall that has only 1 item on the menu - coffee. The stall is set up each evening in Ashikaga City, Tochigi Prefecture, and has been a popular haunt for locals and visitors for almost half a century. Among the customers we met were: a successful psychiatrist who runs several hospitals; a company employee who always ends his week here; and a man who has been coming here since he was a little boy. For 3 days, we asked the customers about what makes this stall so special, and why they keep coming back.
