Mercurial host Ermes Rinaldi greets you as you walk in and seats you wherever he happens to have room: it doesn't matter that you might be put with people you don't know, since the host feels this quasi-communal style of lunching encourages conviviality. In the kitchen, Bruna, Ermes's wife, turns out splendid versions of cucina casalinga modenesi (home cooking, Modena-style). Ermes recites the short list of primi and secondi on the set-price menu, which change daily and arrive promptly. The accompanying wine is local, simple, and inexpensive: most stick to Lambrusco. It's no surprise that this rough-and-ready place is favored by everyone from suits to construction workers to students. Come early to get a table, and note that bookings are not accepted.
