The first Singapore location of this Aussie gourmet burger restaurant is a sleek and modern space with natural wood, cowhide and stone accents. Expect burger patties made from Australian wagyu beef sandwiched between fresh baked buns (including gluten-free options). The most basic is the Classic Charlie Burger ($15), which comes with a choice of aged cheddar, brie or blue cheese. The Mighty Charlie Burger ($17), on the other hand, is tricked out with aged cheddar, prime back bacon, egg and aioli.
