Bistro Union puts the ‘great’ in Great British food. 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.
