What term did Romans use for a place that sold hot food and drinks?

The term "thermopolium" specifically refers to an establishment in ancient Rome that sold hot food and drinks. These were crucial social spots for the lower classes and those who may not have had full kitchens at home. Thermopolia typically featured a counter with large storage vessels embedded into it, where patrons could purchase ready-to-eat meals and warm beverages. These places were especially popular in urban areas and often served as important gathering spots for community interaction.

While "taberna" can refer broadly to any shop or inn, "popina" usually indicates a more casual dining establishment serving food and drinks, often with a focus on socializing. "Salon" does not apply in this context, as it generally refers to a meeting room or gathering space, particularly in a more modern context. The specific focus on serving hot food and drinks in the "thermopolium" differentiates it from these other terms, making it the most accurate choice.
