There's nothing better than punctuating a Sunday afternoon with a large, leisurely lunch. That's why we've teamed up with Coal Rooms, a brand-new restaurant in Peckham from the team behind the lauded Spike & Earl and Old Spike Roastery, to offer Foodism readers 50% off its Sunday roast menu for one day only – with a free glass of red or white wine thrown in, too.

On 3 September, between 12 and 5pm, you can get an exclusive glance at the Sunday menu and tuck into dishes like treacle and beer-cured pork ribeye, slow-roasted shoulder of Daphne's lamb or a sharer of Norfolk Black chicken with sourdough sauce, all served with beef dripping potatoes, roasted carrots and gremolata, hispi cabbage, creamed leeks, red wine 'Barney Mcgrew' and Yorkshire pudding – and all for half price. You can't say fairer than that.

To book, phone 020 7635 6699 or email james@coalrooms.com, quoting Foodism x Coal Rooms. For more information: coalroomspeckham.com
