I have been to barbeque nation J P nagar branch.Liked their concept for barbequed starters both veg & non veg it was mouth watering & great service not too late not too early .It was noisy so if you are planning for a couple evening you may not get privacy but good for get together.
I would say main course was also good with variety but was little disappointed with dessert section where some more fruit varities could have been added especially for those who are health conscious like me! other than everything was perfect & value for money...!
