While in Springfield, we ate (twice if you MUST know) at a Springfield institution....Andy's Frozen Custard.  I had the same thing both times....vanilla frozen custard with bits of candy cane and Askinosie dark chocolate.  This type of chocolate is made by a local chocolatier who was once a lawyer, but left that to make chocolate.  What I like about it is that it is not very sweet....in fact almost bitter.  Which is a nice break in this decadent treat...that I had twice (and as you can tell, feeling rather guilty about that at this moment!).
