The chef personally heads to Smithfield/Billingsgate daily to procure foodstuffs for sushi/sashimi (yellowtail, scallop, sea urchin, sweet prawn...), plus bamboo-skewered robata like bacon-wrapped Ekoni 'shrooms, minced beef w/ veggies, and chicken skin, a move Colonel Sanders would call "cutting out the middleman". Lunch bentos -- size-upgraded for dinner plates -- are all grilled before your eyes, and pull in the likes of Scottish sirloin, teriyaki salmon fillets, sea bass grilled with olive oil, and garlic-chilli-soy "super tender" pork belly -- if you're going to share a prison cell with a pork belly, you definitely want it to be this one.
The bar's got a wide variety of eastern liver-punishment: cocktails are coming, but for now there's beer, wine, sake, chilled Shoshu ("Japanese vodka" distilled from barley, sweet potatoes, or yuzu) and "Umeshi" plum wine -- which whether you live in a town, a city, or a...townty, should be just the thing to Brighton your day.
