shake shack burgers

there are a lot of outlets of shake shack in Singapore these days , such as jewel which is located at changi airport , vivo city , great world city , orchard etc . tried the great world city outlet and the ambience is just amazing and nice. very spacious and big outlet and lights were very bright and inviting. had the beef burger and the vegetarian mushroom burger. both were really very good. for the beef burger the meat was really delicious and tasty!! the mushroom burger has cheese filled with it and it was perfect. overall would recommend dining here at least once and it is definitely worth the bucks.
