Shine in Hisaronu was worth the trip once a year when you just needed something curryish but people must be deluding themselves to say these places are "authentic" or even more far fetched "the best Indian I've had".
They are at best on par with a jar of Loyd Grosman's (which rumour has it some of them are
) If I've been to 100 Indian restaurants in the UK, Shine, while satisfying a basic pang annually, comes in as the 101st best.
