I'm out of date, but certainly in the past Tandoori Nights was easily the best. Foxy talks about "many years back", I don't know how many, but I do know that I used to go for curries a lot in the area, and TN was a cut above (and you didn't mind paying a bit more).

Was never a huge Mirash fan, and always quite liked the Curry Cabin, but that may be more down to nostalgia (first ever curry there).

I think it's basically down to personal taste.
