The shack burger indeed live up to its hype. Piping hot angus beef patty was superb and the bun is soft. Having tried Omakase burger, Three Buns burger, Aston beefy jack, mc donald cheese burger and carls junior, I rate this shack burger as one of my all time favourites at $9.20. But having said that I could have eaten 2 at 1 go as it isnt a huge burger. I queued for 1 hr 15 mins and 15 mins to collect my burger. I would definitely come back again when the queue subsides. 😄 #shackburger #shakeshacksg
