According to Chicago Eater it looks like they're having another interesting promotional twist in honor of Valentine's day:
Sure, everyone thinks Valentine's Day is just about love. But it turns out that St. Valentine is also the patron saint of bee keepers who often had roosters hanging around him (at least that's how it's shown in iconographic images). On top of that, Feb. 14 is also the ancient pagan holiday of Lupercalia, a celebration of fertility where people would often sacrifice a goat.
From this, Custom House Tavern chef Perry Hendrix is crafting a four-course meal ($44 a person) that pays homage to Valentinus and Lupercalia, where each course will somehow tie in either honey, rooster (sort of) or goat. The menu, which will be
served Feb. 11-14 alongside the restaurant's regular menu, will feature items like soft-boiled egg, coq au vin, braised goat shoulder and hay honey parfait for dessert.
