Small plates dining at small prices
Eating in E7 is more synonymous with the curries of Green Street than small plates dining, but now Masterchef finalist Michael Saunders' Milieu is at independent cafe Coffee7, there's an excellent reason to head to Forest Gate. The regularly-changing seasonal menu from head chef Alex Goulding (brother of pop star Ellie) includes free-range, organic meat and fish, and locally-sourced veg. To match the informal atmosphere, there's a well-chosen drinks list including small-batch brews from nearby Wild Card and natural wines. The best thing? The prices are extremely reasonable, meaning your bill will probably be as small as the plates.
While Coffee7 is open every day, Milieu serves Wednesday-Saturday 6pm-11pm. 10 Sebert Road, Forest Gate, E7 0NQ
Sunday 23 April
LONDON MARATHON: It's Marathon day! Why not head to somewhere along the route to cheer on those hardy runners (and see how many ridiculous costumes you can spot)? We'd recommend avoiding Greenwich and Tower Bridge, as these areas are busiest with spectators. Even if you're not watching the race, be aware that road closures will be in place all over London — more information here. And if you're running: we take our hats off to you. Mass race starts at 10am
FLEA MARKET: Get your hands on some vintage bargains at The Big London Flea, an indoor flea market with 50 traders, a food hall, a sound system and more. Epic Dalston, free, just turn up, 11am-6pm
KILL IT, EAT IT: Sounds reasonable enough, right? Foodie wizards Bompas & Parr's latest offering aims to get people thinking about what ends up on their plates — by killing it before they eat it. Each participant will be given their own crab for a workshop on humanly despatching crustaceans. Sea Containers, £45, book ahead, 11am-1pm
ST GEORGE: St George is being celebrated in Borough Market today — a rare treat, as the market is normally closed on a Sunday. He's the patron saint of Catalonia as well as England, so both cultures are being celebrated through food, music, storytelling and theatre. Borough Market, free entry, just turn up, noon-4pm
FAMILY RAVE: The ultimate party for kids and their parents is taking place at this daytime family rave, Big Fish Little Fish. They've bagged a big-time DJ too, in legendary Fabric resident Terry Francis. Mangle E8 Nightclub, £9/£6/free, book ahead, 2pm-4.30pm
CONSTABLE TOUR: John Constable spent much of his time in picturesque Hampstead; see the places that inspired his work as well as his family tomb. Hampstead Station, £12/£9, book ahead, 2.30pm-4.15pm
COMPETITIVE PAINTING: Some people feel that art should be judged on its own merits, not compared and contrasted with other works to decide what's superior. Well, that's not how Art Battle London feel, as the audience decides which of the 10 pieces created live is the best. Kamio, £15, book ahead, 6pm-11pm
Fun things to do with our friends and sponsor Funzing.
