I’ve been meaning to check out Logan Square’s Provenance Food and Wine for a while now, but I may actually get around to it this weekend. Saturday the store hosts a book signing with Jean Iverson, editor of BYOB Chicago: Your Guide to Bring-Your-Own-Restaurants and Wine and Spirits Stores in Chicago.  The second edition of her guide to more than 150 BYOB restaurants as well as the best places to pick up a bottle along the way came out last month. The afternoon also features a wine tasting and snacks from Treat. It’s from 3 to 6 PM at Provenance, 2528 N. California.
