Great burger - got the One Red Door and loved it. Juicy and tons of flavor. I saw at least 4 other burgers I needed to get. Don't skip the fries - truffle oil and cheese were amazing and enough to share. Milkshake wasn't great and boozy add in didn't last past first sips. The only problem with Flip Side is straw diameter - seriously small for pop and far to small for chunky milkshakes. I need a hose ppl!! Nice staff and great atmosphere.
