This Saturday (and 12/12 and 12/19) from 2 to 4 PM the Hotel Allegro (171 W. Randolph) offers free treats and pictures with “Santa Paws” in its lobby. The hotel will also give pet owners $20 gift certificates towards an overnight stay. The event is BYO camera; Santa will pose with most pets, but spiders, snakes, and rodents should stay at home.
