Burger is not my favorite food but I do try once in a while... I never heard Shake Shack since I never see them here in Philippines.. My favorite burger that I've tasted is the 8 Cuts Burger Blends in Greenbelt Makati... The burger is very huge can't fit into my mouth LOL..
The fries makes me wanna taste it later not maybe as good as that but I am curious now and want to mix it with cheese.. :)
Have a nice day..
