There are still no Sonics in Washington state* but it looks like my home state of Minnesota is getting one, despite its most un-drive-in-like weather. Rob and I have a message for all our Minnesota friends: Familiarize yourself with the Sonic icy drink menu. The food we've tried? Well, let's just say it's fun to explore the menu, but it's no In 'N' Out.
Online sources have many recipes for the famed cherry limeade, if you're interested. It's unbelievably simple, but it's better at Sonic, with their super-crushed ice.
*Whoops, turns out there ARE some Sonics in Washington state, just nowhere near me. Didn't mean to slight you, Spokane! I will hoist a cherry limeade in your honor next time we get over there.
