Margaux is a relatively casual but still elegant neighbourhood restaurant serving Euro bistro-style food, and they do it well. Dishes like the roasted duck breast or venison fillet are very good. It’s one of those restaurants that is good for literally everyone, so you can be safe in the knowledge that if you were to bring your nan, a random internet date, or your boss here, they would all have a great time. They might find it weird to be sat at dinner with each other though.
