4 Seasons Bakery in St. Charles, owned by Agi and Aaron Groff, specializes in pastries, pies and other baked goods. From their tiny storefront, the Groffs have been producing some of the finest pastry in the area, using only natural ingredients. Their macaroons and Linzer torte are rightly lusted after. But it's their pie we swoon for. The crust has achieved the perfect medium. The fillings, made from seasonal fruit, are good, too: sweet but not cloying.
