There is a collection of graffiti from Pompii that includes references to bars, restaurants, and where to get the best food and drink. I'm sorry I can't find the Latin for you, but there is an old page with excerpts translated into English that give the CIL numbers [here] (http://www.pompeiana.org/resources/ancient/graffiti%20from%20pompeii.htm).

Here are a few of the relevant passages.

III.5.4 (exterior of a small house); 8903: Gaius Sabinus says a fond hello to Statius. Traveler, you eat bread in Pompeii but you go to Nuceria to drink. At Nuceria, the drinking is better.

I.14.36 (Bar of Salvius); 3494: In one bar, a picture depicts two men playing dice. One shouts, “Six!” while his opponent holds up two fingers and says, “No, that’s not a ‘three’; it’s a ‘two’”. By the door of the bar, another picture shows a short man driving a group of men out. Above his head are the words, “Go on, get out of here! You have been fighting!”

VI.14.36 (Bar of Salvius; over a picture of a woman carrying a pitcher of wine and a drinking goblet); 3494: Whoever wants to serve themselves can go on an drink from the sea.

VII.2.44 (Bar of Hedone (or Colepius) on the Street of the Augustales; on the corner toward the lupinare); 1679: Hedone says, “You can get a drink here for only one coin. You can drink better wine for two coins. You can drink Falernian for four coins.”

And here are some just fun ones.

I.2.23 (peristyle of the Tavern of Verecundus); 3951: Restitutus says: “Restituta, take off your tunic, please, and show us your hairy privates”.

III.5.3 (on the wall in the street); 8898: Theophilus, don’t perform oral sex on girls against the city wall like a dog

IX.8.3 (House of the Centenary; in the latrine near the front door); 5243: “Secundus defecated here” three time on one wall.
