"A rapidly expanding American mega chain somehow beats most homegrown burger restaurants in London. One just needs to know what to order, or rather, how to order the trademark Shack Burger. It’s pretty simple (if emulating classic fast food burgers is the goal.) To best complement the beautifully and aggressively griddled American cheese-covered patty, which is sandwiched between a sliced, squidgy Martin’s potato roll, order sliced raw onion and add pickles. (Tomato should be optional.) The original branch in Tourist Central, Covent Garden, is the pick of that area’s restaurants." - Adam Coghlan, Emma Hughes, James Hansen
