Oblix

You're 800 feet up, looking down at the Thames snaking through south London, and there's a cocktail in your hand. Oblix splits itself between a proper restaurant and a livelier bar scene, so you can go serious with dinner or just roll in for drinks and some seriously good snacks. The menu leans into modern British cooking—think roasts, seafood done right, seasonal veg that actually tastes like something. It's dressed up without being stuffy, which is honestly harder to pull off than it sounds. Yeah, you're paying for the location, but the kitchen's actually trying.
