I would agree with that, J2K — even when curry was my be-all-and-end-all, a four-hour journey for what I
hoped could turn out to be the perfect curry would seem somewhat excessive. Let me cast my mind back to my halceon days in Kent and see if I can remember somewhere to recommend that might meet your expectations ...
Well, it's not old-school BIR as I remember it from the 60s and 70s, but it was still my preferred location for BIR when I lived in Kent — the
Raja of Kent in Tenterden. Otherwise take yourself off to Ashford, which has a large ex-Ghurka population, and sample the offerings there.
