Hey Connie - How about the banana/poppy at Once Upon a Tart on Sullivan?
And speaking of poppyseeds, can anyone recommend a really terrific poppyseed cake/bread/muffin? I like them dense. There used to be a wonderful place out in the avenues (Mary's @ 25thish) in SF that made a great "russian" bundt poppyseed cake.
Have to admit I've never had the Cupcakes' muffins, since if I'm in weakling mode, I go for the oat donuts.
