Recently I was at the "Margaritaville" bar at Navy Pier in Chicago. It was kind of an odd experience because at first they weren't playing tiki-bar style music (I think I heard some Pearl Jam) but then they fell into the summertime breeze tunes that were expected.
However I had to laugh while looking at the menu. All of their booze comes right out of their own brands. Plus they own "Landshark" beer, as well, I think. This is "vertical integration" at its finest.
