Pease's is a totally different experience than Del's. Where Del's is all old-timey, Pease's is like a laboratory, all white, glass, and stainless steel. Pease's and Del's offer many of the same candy and popcorn items, but Pease's does molded chocolates (Abe Lincoln, surprise surprise) and chocolate bars. You can also watch the candy makers through a glass window. I spent another $13 on candy to try.
From least favorite to most favorite, I tried:
Raspberry Dollars: they were fine, not too sweet, not to raspberry. Good candy to sneak into a movie.
Mint Melt-Aways: I liked these a lot. I love a mint/chocolate combo generally.
Raggedy Anns: YUM. I think these might be their specialty. A sublime combination of carmel, pecans, and chocolate.
Dark chocolate covered blueberries: Man, these were DE LI CIOUS. Just the right combination of sweet and tart. But at $6 for maybe a cup and a half, they were the most expensive treat I bought at either store.
Look! You could throw a kid's party there. Not cheap, but it looks like an experience they would remember.
