Lucky Star was an all you can eat Chinese buffet. (It has now been replaced by Nines). On Saturdays at least they seemed to have coachloads of Chinese tourists calling in, guess that is good business for them.
The food was different in that it was Chinese in design, and being a buffet one could get fed quite quickly. It was disconcerting one time when we were hovering, thinking about where to eat, and the manageress almost tried to drag us in physically.
