Impulse :) - Regents Park is in Central London. Heathrow is in outer suburbs of London, many miles away. To get to Regents Park will probably take you 50mins or so by train/tube. But yes, there are many many asains in the area around the airport - Hounslow, Ealing, Southall (a dump) and Hayes. The desi community is huge.
