3.5 stars for Siddhartha.
Our group of 5 decided to have the buffet dinner ($14.95pp). There were several empty tables when we arrived.
The selection of items consisted of the traditional items: tandoori chicken, butter chicken, paneer tikka, channa peshawri, aloo ghobi, etc...We found the food to be fresh and flavourful. Our server brought out a a fresh basket of garlic naan for our table which was crispy and warm. Overall, I thought the food was fine and exactly what I expected.
Atmosphere is cozy and inviting; you could sit for a few hours, have a drink and nibble away. Don't do what we did - gorging too fast will only result in a sore stomach!
