Boisdale of Belgravia
Having been around since 1989, Boisdale of Belgravia is an old-school gem that's decked out in sultry red interiors, complete with plush velvet seating and decadent chandeliers. They host a regular lineup of live music here, particularly jazz, blues and soul.
Whether you're dining inside or on the heated roof terrace, there's plenty of hearty British fare to enjoy. They specialise in seafood, with everything from grilled lobster to wild sea bass on the menu, though there are plenty of meat and plant-based options too.
