We had seen the Kalpna had an all-you-can-eat buffet while we were visiting Edinburgh and so decided to fill up on our last day before we took the train out of town. When we arrived with our suitcases, we were kindly shown a place to store them out of the way. Checking out the food, I noticed there were a good number of reasonably different salads, puri, cauliflower and potato (separately) pakoras, rice and three curries (lentil dhal, chickpea masala, mushroom and spinach). All of these were vegan except one yoghurt dish and this was confirmed for me by one of the helpful staff. We were encouraged to eat as much as we wanted and there was nothing to give us a sense that we should stop eating after a polite amount. As it happened I didn't have a massive appetite on this occasion, but I still felt I got a good deal for £8. I'd come back regularly for a decent lunch.
