A former sign-making shop is now a bar with no sign. Add to the irony: Aside from a couple of grandma’s mid-century-styled couches, there isn’t much to make this subterranean lair — also once a bean-sprout factory — feel like home sweet home. At best, aficionados of taxidermy and lovers of knickknacks will feel like they’ve paradoxically climbed down a stairway to heaven. The wooden bar’s illuminated dioramalike display cases show off eBay detritus like a de-necked electric guitar, dental casts, and the disembodied horse-head of a hitching post. As far as real animals go, a stuffed rabbit, an eagle, and a beaver frolic around a tree branch repurposed as a lamp stand. That sort of exoticism doesn’t carry over to the beer selection or to the DJ’s jams (which run the gamut from Skynyrd to the Smiths).
