China Moon Buffet

We have been regular customers here for around 2 decades.
The food was always well prepared, tasty & plentiful.
We noticed it keeping lower standards over the course of many visits during the past 12 months.
Today we went again, made sure to arrive as close as possible to their opening time (11AM) for the very freshest foods on their buffet.
The quality was definitely even lower, dishes & condiments were left unfilled, and the woman in charge was aggressively argumentative when asked for help with these normal items.
We will not be returning to this restaurant.
