I've grown up with custard cup, and I love it. I prefer it to Penn State's Creamerie which is apparently blasphemy, since PSU taught Ben & Jerry how to create delicious.
My favorite thing about custard cup is how willing they are to work with you-- I like to get raspberry cobbler snowstorms, but with lemon instead on vanilla custard. They'll do it for you. Peanut butter cup with chocolate? Yes indeed. You can create some utterly delicious things, and they've never told me no in my craziness, including combining multiple snowstorm flavors. I highly recommend that people check out Custard Cup, it's totally worth it. Don't be scared of lemon, it's it's heavenly.
As a note: No credit cards, only cash or check. Closes at 10, so not so much for the late night cravings.
