I never considered ice cream as a snack but I go with neopolitan especially with real strawberry bits. A nice balance of sweet and bitter (from the chocolate). If my local grocery store sold neopolitan flavored ice cream sandwiches, I buy those in a heart beat and probably eat the entire box in a day XD
But for snacks I like anything crunchy and salty, or fresh fruits like grapes and clementines. I'm so hungry now.
Coffee-flavored with big ol' chocolate hunks. Now that's the shit.
Edit: I'm referring to fave ice cream if that wasn't apparent. From the poll i thought this was an ice cream thread, but from the title I'm not so sure... Whatever, try coffee ice cream.
