On a saturday afternoon, it was about 15minutes queue and 30minutes wait for food. The shack sauce was irresistibly crramy and matched with the grilled patty.
We had to get the mozarella cheese fries, which tasted milky and may get gelat - theres also tomato + mustard to mix and match. ($28 in total)
Still a little not sure what I'll eat when I come back to Changi airport next time. Excited that all these international fast food chains are coming to Sg. (in-and-out! Five guys? Tim hortons?)
