Sweet Mandy B's is an absolutely must-try in Chicago. They carry all sorts of sweets, like cookies, brownies, and cakes, plus coffee, pop, and milk. Seating is kind of limited but very cute, and if you go on a weekend be prepared to wait in line! My absolute favorite items are their cakes (white cake with white icing, or chocolate cake with chocolate icing)... They are moist, sweet, and the icing is fantastic. Also try the homemade Whoopie pies... they are delicious! (But I believe they sell out quickly.) They are a bit expensive.... a slice of cake is around $3... but it is worth it!
