This burger is just DA BOMB. I mean really, it's almost as awesome as the Shack Stack. Then again, it's probably because it was my own custom made burger. Not only was it filled with mushroom-y goodness, the patties were really juicy and cooked to perfection. A new joint, #BurgerUpSG offers a refreshing concept that allows you to either choose from their default menu, or create your own one-of-a-kind through a touch screen menu. As much as this would be a great opportunity to grow, I think they should also allow payments at the machine (eliminating the middle man altogether, while effectively promoting a fast and efficient service). Definitely worth a try, can't wait get my hands on this again. #burgerupsg #burgerupsingapore #yishun #shareats (at BurgerUp)
