If you're really looking for fairly standard and simple stuff, you're pretty close there to Bar Zaika Bazaar (2A Pond Place / 020 7584 6655), which is related to the high-end and successful (Michelin starred I think) contemporary Indian restaurant Zaika, but with a more trad menu and lower prices. I understood it was meant to do a sort of tapas, but when I went it had a starter-and-main-course kind of menu. In the West End, there's Masala Zone off Carnaby Street (9 Marshall Street / 020 7287 9966), an 'Indian Wagamama' from the Chutney Mary people. Food is okay; depends on your standards, which depends where you live ; but it's accessible, fast, friendly and good value. And I remember there's butter chicken on the menu. Otherwise, you could go in two directions -- either out of the centre, to some of the restaurants based in local communities like Sri Krishna and Kastoori in Tooting (the latter good East African/Gujarati vegetarian food); or upmarket, to some of the newer, finer-dining places that are winning a lot of plaudits recently (like Zaika, Cinnamon Club, the revamped Red Fort), but this may indeed be getting 'fancy'. Just steer clear of Brick Lane, with the possible exception of the Lahore Curry House.
