Lasdun Restaurant
You can't get much closer to the action than Lasdun, as it's nestled within the National Theatre itself. This contemporary British brasserie was created by the team behind The Marksman in East London, promising modern, understated interiors and a welcoming atmosphere.
Their pre-theatre menu offers two courses for £32, or three for £38. Think smoked haddock fishcakes, roast onion tart or crab soup, with creme caramel shortbread for dessert.
