With a pretty concise menu, Gyu San Charcoal Bar’s Hamburg Set ($23.80) was quite the substantial treat - great for slow and big eaters who can fill up with the free-flow rice as well as miso soup. Expertly grilled over the binchotan charcoal grill and served on a personal mini grill to keep them warm, the two 90g wagyu patties were both tender, succulent and juicy. Packed with finely diced onions and other seasonings, the patties were also wonderfully flavoured and especially so with the charred exterior. Overall, great even without the small array of condiments and not too greasy or cloying.
