These guys.
They took over a corner building in a busy shopping street here that had one shop/restaurant after the other. For some reason everything failed there.
Now everytime i walk past their little restaurant i see a gold mine. It's ridiculous. While across the street a whole street full of restaurants has hardly any customers these people can hardly handle all the orders they get per minute.
