The signs of Fall are certainly approaching as Starbucks has reintroduced its seasonal Pumpkin Spice lattes. The crowds are flocking for a taste of this sweet, pumpkin-pie-like beverage, but the demand is high, the price is steep, and the lines are long.

Which one reigns supreme? The results may satisfy you or they may take you by complete surprise . . .
