We will be staying at the CS on Michigan Ave next week, and once our shuttle drops us off at our hotel, we'd like to find a place where we can pick up some liquor and beer to enjoy in our room. Without walking too far, is there someplace close we can grab a 12 pack? I've read there's a Walgreens fairly close, but do they sell beer? I highly doubt they sell liquor (the ones here in Vegas do not), so a liquor store close would be handy. Any suggestions and info is appreciated. Thanks!
