For most of my life, I lived on the Eltham/Chislehurst (=London/Kent) border, and there was one T/A near my home on which I could always rely. I moved to deepest Kent about ten years ago, and although the nearest Indian restaurant was truly superb at that time, it is now little better than mediocre. So, passing through Eltham on my way back from Tower Bridge tonight, I thought I would stop at that T/A and revive my taste buds with a first-class curry. Sadly I was wrong. The chicken tikka starter was a generous portion, and certainly OK, but not really excellent. The pulao rice was almost without aroma or flavour, and the chicken Madras just average. One dish, however, stood out head and shoulders above the rest -- the sag aloo. Beautifully dry, totally distinctive flavour (/definitely/ no so-called generic "mix powder" in its spicing), and really to die for. If only the other dishes had been as good.
