Is Chicago ready for its first all-cupcake bakery? Apparently so. Cupcakes, the logically-named patisserie in Lakeview, sold out of all of its 37 varieties within four hours of yesterday’s grand opening. They then re-opened at 8:30 in the evening, and promptly sold out again. Head to 613 W. Briar to see what all the fuss is about (though you may want to check the cupcake stock at 773-525-0817 before you show up).
