Eating outside is all very well in this weather but it kind of spoils the vibe when you're inhaling traffic fumes along with your Pimms and seared tuna. Which is why it's always worth remembering more secluded, yet conveniently central, spots like Heddon Street in Mayfair.

To make the charmingly cobbled Parisian-style patch even more enticing, Momo (the place that put the street on the map in the first place) is celebrating its tenth anniversary by offering a new, expanded menu at Mo Tearooms, the more laidback alternative to eating at the restaurant next door.

You may not get the same late-night hip-shaking action in the Tearooms but you can get crispy king prawns with avocado hoummus, filo parcels of smoked haddock with coriander pistou and other delicious Middle Eastern mezze.
