Bistro Union is hidden away at the far end of Clapham Common, a short walk from Clapham South tube station and is another joint from Clapham legend Adam Byatt. By mid-evening the restaurant is full of professional young Claphamites – some enjoying the full menu, others just dropping in for drinks and bar snacks. It’s a quintessentially British menu, with everything from Welsh rarebit to steak and chips to Cornish mussels cooked in perry cider. Service is very friendly and well informed, with staff able to talk about the ingredients and their provenance. Bistro Union puts the ‘great’ in Great British food.
