Gaku Hall is an izakaya in Tsim Sha Tsui serving Japanese food and drinks. Its signature dishes are a salmon roe and sea urchin cup and thick slices of pink beef tongue, along with wagyu foie gras rice in a pot and seaweed tempura tacos. Staff finish the pot rice and a thick cheese-sauce rolled omelette at the table with a blowtorch, and guests take off their shoes to use the tatami seating. Diners are still waiting past 9 p.m., so seats run short late in the evening.
