In case it isn't obvious, "AYCE" means "All You Can Eat". Not all buffets are — although sometimes people assume they are — so note if they are or are not. Also, not every All You Can Eat meal is a buffet — some are served by waiters (a buffet means guests serve themselves). The rule is that if you are served, you are expected to give them a tip. If you serve yourself (buffet), you are not expected to leave a tip.
As of July 2022, there are no buffets in Davis open for dine in because of COVID-19 besides the Segundo Dining Commons. It caters towards UC Davis residence hall residents, but they are also open to the campus community and the public.
