If your heart skips a retro beat at the thought of old-school milkshakes, whoopie pies, and 1960s leopard-skin pants for a song, you'll want to pay a visit to this way-cool Arcadia shop, which has them all. Owner Trejsi Mulac is usually manning the soda fountain, where diners belly up with cherry-topped sundaes, fizzy sodas, and signature shakes such as the feisty Sophia Loren and the Adam 12, made with chocolate malted crunch and a shot of toasted marshmallow. Resisting the glass cake stands filled with daily changing homemade delights like brownies, cake pops, and whoopie pies is futile — as is the shopping. Those leopard-skin pants aren't going to buy themselves, you know.
