Sleek minimalist restaurant in the heart of St James', The Avenue is ideal for lunch.

The clean, unfussy decor and besuited clientèle make this a little cold for a romantic evening meal, but for a slap up lunch on expenses it's pretty much spot-on.

Food is Modern British/European, so pretty generic London restaurant fare, but done well with excellent attention to detail. You can get three courses from the set menu for £21.95 so it's pretty reasonable too.
