We ask a London expert to give us their Top 5 for the best in the capital's shopping, dining, nightlife and more. Laura Porter, aka @AboutLondon, shares the best street markets for foodies.

Borough Market 

The grandaddy of them all.

What's it like? London's oldest food market is rightly the most popular. Meet the producers who farm organic meats, create artisan cheeses and bake organic bread. It's a permanent Victorian covered market that's crowded on Saturdays but always worth exploring. See, try and buy the best seasonal produce as there are always samples on offer to help you select the freshest riverside picnic, or choose from the tantalizing aromas of hot street food.
Who goes there? Close to London Bridge and the South Bank, this food market is loved by Londoners and tourists alike for its top quality produce. 
Why I love it: A glass of Sangria from Cartwright Bros and olive tasting at The Turkish Deli make every lunchtime special.

Maltby Street Market

A more intimate Borough Market.

What's it like? Local produce rules at this small weekend street market, with smoked salmon from east London and gin distilled in south London. Sandwiched down a paved avenue lined with Victorian railway arches, festooned overhead with brightly colored bunting, this market has that 'secret find' vibe. The arches have bars and restaurants too and outdoor seating encourages you to stay and be part of something special.
Who goes there? Foodies who want to be seen at the right market without the crowds.
Why I love it: The best Bloody Marys at the Little Bird Gin pop-up bar, sublime grilled cheese sandwiches from The Food Truck, and gooey salted caramel brownies from Bad Brownie.

The Landmark

Hackney hangout for young hipsters.

What's it like? This Saturday-only street market is ideal for sleep-deprived parents in need of a cup of trendy small batch coffee to wake up to the weekend. And foodies will love the spices, cheeses, breads, rare-breed meat, cute cupcakes and sumptuous olives, whilst the cool kids will adore the vintage clothes stalls and organic fair trade products. The street is lined with cafes and restaurants and The Schoolyard Market, near the Cat and Mutton pub, has great street food.
Who goes there? East London's fashionable hipsters and yummy mummy families.
Why I love it: Gorgeous cupcakes from Violet and chilled Vietnamese coffee from Cà Phê VN combine perfectly with lounging on the grass in London Fields.

Broadway MarketLocation: Broadway Market, off Lansdowne Drive, London Fields, London, E8 4PH. (Broadway Market runs from London Fields park to the Regent's Canal.)
Hours of Operation: Saturday 7am-7pm

Whitecross Street Market

Lunchtime street food at its best.

What's it like? World cuisine is well represented here with Thai, Indian, Vietnamese, Italian, Brazilian, Mexican, Turkish, hog roast and more. Traffic-free during market times, this is the place for the freshest street food cooked in front of you. Lines start around midday and stalls start running out after 1pm on Thursdays and Fridays. This is real worker's fare so expect generous portions and often change from a fiver.
Who goes there? Near to Old Street, the market gets regular trade from the local office workers at Silicon Roundabout.
Why I love it: So much to choose from and so cheap! Burritos from the Luardos 'Mexivan' are superb and the veg thali from the popular Indian stall is perfect to share. On more virtuous days a Buddha Bowl is a healthy vegan treat.

Whitecross MarketLocation: 1 Whitecross Street, London, EC1V 9AB.
Hours of Operation: Monday-Friday 10am-5pm

Southbank Centre Market 

Top South Bank location.

What's it like? Around 40 curated stalls make up this open-air foodie heaven of street food and fresh produce. This is quality over quantity with meat specialists plus amazing cookies and chocolates. The craft beer or fresh juice is a great accompaniment to sausages, sliders or cheese samples. 
Who goes there? Londoners and tourists love London's South Bank so you'll find a good mix of holidaymakers and locals enjoying al fresco nibbles.
Why I love it: The location can't be beaten and neither can the Frenchie Duck Confit burger with Truffle Honey cheese topping. If the seating is taken, wander round to Jubilee Gardens for iconic views.
