Great Birthday Cake in or near Floral Park (Nassau), NY?
That's too easy. Get thee to Buttercookie on Jericho Tpk. in Floral Park.
That's the only place we go to, and we live all the way down on the South shore of LI. They have outrageous cakes made with real ingredients-try the hazelnut/chocolate combo mousse-cake.
Don't know much about their other stuff-a relative turned us on to their cakes-and they rock!
