Thermopolium storage pots
Italy picture - "The thermopolium served hot food and mulled spiced wine (calida) from earthenware jars set in the counter. Such an establishment could be a neighborhood stand specializing in two or three items, such as wine, lentils, meats, or cheese, or a more elegant setting with frescoed walls decorating the dining area. Patronized by those who did not have the facilities to cook at home or chose to take their afternoon meal there, the thermopolia also were the haunts of more disreputable sorts. Plautus, for example, speaks of effeminate Greeks and thieving slaves frequenting them" (Source: http://penelope.uchicago.edu/~grout/encyclopaedia_romana/wine/thermopolium.html)
