I've been eating at Delhi Palace for years and it is pretty decent north Indian food. Nothing to blow your doors off, but good enough. The lunch time buffet can be hit or miss, but when it is "on" it is oh so good. Tandoori chicken, tikka masala, palak paneer, garlic naan and pakoras are some of my favorites. They also serve a hot tea and I am not sure what it is called but it goes really well with the spicy food.
When I am not dining for lunch the mushroom bhajee or seafood tandooris are my dishes of choice. Don't fool yourself into thinking the veggie options are going to be good for you. Most of their dishes are loaded in cream, ghee or paneer so diner beware, it is easy to pack in over 1,000 calories in a sitting.. Make sure to top it off with a flying horse lager. This beer is so good I usually order one to go!
