Seabar, Millennium Dome, London (020-8331 4322, information only). Daily 11.45am-6pm. After paying £20 to get into the Dome, Harry Ramsden's kids' meals for £2.50 aren't bad. (Alternatives are McDonald's, Aroma and a New Covent Garden Soup Company counter.) This neighbour of Acclaim (the overpriced "modern-British" restaurant) has some can't-go-wrong fish assemblies. A plate of smoked salmon, smoked halibut and gravadlax is £6.95, potted shrimps £7.75 and rock oysters £1.10 each. If it helps, I saw the Dome's director of marketing eating here.
Heather's, 74 McMillan Street, London SE8 (020-8691 6665). Tue-Sat dinner, Sun lunch and dinner. Only 800m from the Cutty Sark, claim the owners of this dedicated vegan and vegetarian restaurant, which proves the devil doesn't have all the best lines. It's run as a buffet: pay £13 for all you can eat from the imaginative 25-dish spread, ranging from toasted garlic soup, through pumpkin and butter bean stew, to lemon and mint couscous salad. Kids and concessions pay £6.50.
North Pole, 131 Greenwich High Road, London SE10 (020-8853 3020). Bar food Tue-Sat lunch. Restaurant Mon-Sat dinner, Sun brunch. Expect a somewhat baroque look to this pub, where the upstairs dining room mixes grandeur (swagged curtains) with kitsch (goldfish in glass-bowl lampshades). The cooking is modern, rich and robust, but not especially cheap - it's more of a night out than most pubs with food. Veal carpaccio, and seared salmon on potato gnocchi with a creamy basil and coriander sauce, plus a pud, comes in at £20-£25. Set price weekday dinner is £17 for three courses and coffee.
Thyme, 1A Station Crescent, London SE3 (020-8293 9183). Tue-Sat dinner, Sun lunch if booked. This restaurant at the back end of Greenwich got in first with the fourth-dimension pun. Plenty to tempt on a short menu, and the cooking has impact. Pot-roast pheasant and bacon with celeriac mash, or slow-cooked belly of pork with coriander stir-fry, are two typical main courses. Chocolate cheesecake or apple and rhubarb crumble are chunky desserts. Allfor less than £20.Reuse content
