cheap and good near Maida Vale and Kensington Square [London]
right, you must be living in the hostel on ken square. if so, welcome to 'hood, neighbour.
whats your budget? in any case, check out al dar and ranoush on ken high street for lebanese, piccola dely on stratford road (which is off marloes road) for deli style italian, mohsen on warwick road for iranian and bosphorous kebab house on old brompton road for turkish (kebabs). also, just past edwardes sq on ken high street are three iranian grocery/deli's which are very student friendly.
a bit further afield, you can crash the malaysian student hall in queensborough terrace (bayswater).
let us know how you get on.
