For so many Chicago families, it wouldn't be a celebration without a colorful, three-layer buttercream cake from Roeser's Bakery on North Avenue in Humboldt Park. In 1911, John Roeser Sr. opened the doors of his American dream: a bakery filled with sugary delights! Over 100 years later, the city's oldest family-owned retail bakery is still one Chicago's favorite places for a sweet treat.
