From a posh pop-up bakery to Michelin-Star-standard food in a London pub, London’s food and drink scene never stands still. Here are some of this week’s most exciting new openings.

Fortnum & Mason’s Pop-Up Bakery

A pop-up bakery opens today at Fortnum & Mason, selling bread, cakes and pies from some of Britain’s best-known bakers, including chef/restaurateur Mark Hix and Edd Kimber, the first winner of The Great British Bake-Off. As well as delicious treats to take away, there’s a dedicated café, a cookware shop and a series of baking demonstrations and classes. The pop-up bakery is open until 7 April 2013.

The Wheatsheaf in Borough Market

The Wheatsheaf in Borough Market has reopened following a three-year closure. Originally built in 1772, the pub has been given some modern touches, including a campervan kitchen outside on the new heated terrace, where you can buy hearty, street food-inspired dishes.  On the drinks front there’s a wide range of craft beers and ales, including local Meantime Pale Ale and Camden Hills Lager.

The Malt House in Fulham

The Malt House in Fulham has been taken over by Claude Bosi of two-Michelin-starred Hibiscus and his brother Cedric. On the menu you’ll find a range of seasonal British food such as Welsh rarebit, rib-eye steaks and Sunday roasts, courtesy of former Hibiscus head chef Marcus McGuinness. This is the Bosi brothers’ second South West London pub – Cedric has managed the Fox & Grapes in Wimbledon since it reopened in 2011.

Cactus Kitchens: Michel Roux Jr’s New Cookery School

Top chef Michel Roux Jr has teamed up with Cactus Studios – where TV show Saturday Kitchen is made – to launch a new cookery school. You can take cooking lessons with Michel Roux Jr and Masterchef: The Professionals star Monica Galetti, learn about food and wine with Saturday Kitchen experts Susie Barrie and Peter Richards, or celebrate Chinese New Year with Ken Hom.

Look out for more restaurant news soon.

Across the road from the Houses of Parliament, young mixologists Abdulai Kpekawa and Liam Cotter have quietly re-launched Roux at the Pembury.

The smart cocktail bar looks like the kind of place where you might spot a senior member of the House, with leather Chesterfield sofas, Art Deco lampshades and impeccable service.

The bar’s located on the first floor above Michel Roux Jr’s French fine dining restaurant Roux at Parliament Square, which opened in May last year.

Subtle signage means you can easily walk past the entrance without noticing it, as most tourists and office workers were doing when we visited on Monday evening.

We were warmly welcomed by Cotter, who introduced the list of 12 specialist cocktails, arranged as a menu of hors d’oeuvres, plats principaux and desserts.

I enjoyed the refreshing Three Citrus Ricky (Ketel One Citroen, fino sherry, yuzu, lemon, pineapple and soda), while my friend tried the signature Pembury Cup (Pimm’s, Tanqueray gin, watermelon, coriander and champagne).

There’s also a range of posh bar snacks including pork scratchings with smoked paprika, peppers stuffed with feta cheese, and beef and ale pie.

Cocktails cost from £8 to £9.25. If you’re after a little bit of affordable luxury in Central London, I’d recommend a visit to this hidden gem.
