Look, here's the thing about curry in London - avoid tourist trap areas completely. Those guys with menus outside charge premium prices for mediocre curry.

Tayyabs on Fieldgate Street. Been there since 1972. The lamb chops are brilliant and portions are massive. BYO booze, around £20-30 per person. Expect to wait.

Needoo Grill at 87-88 New Road, Whitechapel. Open till midnight daily. Mixed grill for two is £28.95, feeds four people. Cash only.
