Well whenever I have a treat some friends over some good food and nice conversation, we head to Barbeque Nation. Have been to their other outlets as well, and they are all the same. Serving good food.
You just have a barbeque buffet spread, both veg and non-veg. The waiters bring over tikkas and veggies and muttons and chicken skewers, which can be well cooked and leave it over the small barbeque pits fitted on your table. You can grill it with marinates of your choice.
My friends who enjoy non-veg tell me its a heavenly. Non-stop servings to your liking. And then there is a small carefully selected buffet containing both veg and non-veg dishes and biryanis and soups.
Go and give this place a try.
