I went there with some friends for a birthday meal towards the beginning of December and I thought it was terrible. The food was overpriced, and everybody I was with complained that everything tasted the same (we had about 10 dishes on the table).
The service was well below par, the waiters started having a massive argument near my table, then started giving us all attitude when some of us couldn't decide what to order. We could hear them arguing in the kitchen during our meal which wasn't very nice.
I went to that 4550 Miles To Delhi restaurant earlier this month, and it was actually some of the best Indian food I've had from a proper restaurant in a long while. Prices weren't too bad, you could get a banquet style menu for just under £20 a head, and they would refill any dishes that were running out.
