I love nepalese food - at least the UK version, having never been there yet.
The Great Nepalese Tandoori on Eversholt Street on the eastern side of Euston Station is fantastic. A very nice twist on BIR flavours. Their pickled vegetable side dish is to die for. No website though, unfortunately.
That part of London - from there to roughly the BT tower has some really interesting regional sub-continental restaurants.
I have said this before but the variety of the BIR should have its own room. Pakistani, Punjabi, Nepalese, all have specific restaurant styles which are not the Bangladeshi mainstream.Gujerati food, South Indian vegetarian restaurant food, all should be celebrated here.
