What were restaurants called in medieval times?

Answer 1

Peasant houses had no "dining area" and often no separate kitchen; food was cooked and eaten around a central hearth in the main (sometimes the only) room in the house.

In a manor house meals were eaten in the great hall.

In a monastery there was a building termed the refectory, situated next to the kitchens, where monks ate in silence.

Answer 2

In medieval times, there were no restaurants i.e. places whose primary purpose was serving food. Food was general scarce in the middle ages and what good food was available was readily consumer.

People would go to Pubs, Taverns, and Inns where food was served as a side business to all the beer, ale, grog, wine, etc. Selling booze was the primary purpose of these establishments. Inns of course were overnight stays like today.
