I've patronized Bagatelle for well over 10 years and they continue to have the best bakery items in Wichita. Their custom-made cakes are absolutely perfect! I had two for my wedding, one German chocolate and one sugar-free strawberry. It was the best wedding cake I've tasted. Since then, I've also tried the chocolate raspberry, and I think I might like it the best. Keep an eye out for the fudgey rum cakes, they melt in the mouth.
They also provide a nice light lunch, with soup, salad, and rolls.
