You can't go wrong with milkshake from Sweet Republic when your flight is delayed. The sweet cooling drinks here are the perfect sugar rush, the ultimate pick-me-up when you are tired and just want to go home, or if you have a throbbing headache that just won't go away. I like the banana and horchata flavors here - they make great shakes. The staff have always been friendly and let you try different flavors too, which is nice for an airport location.
