The coolest place I know so far as I belong to Lucknow. One thing you get the most over there is Respect by everyone you meet.
The Food in Lucknow is lipsmacking which you can get everywhere like the most famous Tundey Kababi, wahid biryani, Dastarkhawn etc for the people who love non-vegetarian.The list dont ends here, for vegetarians their is Royal Cafe, Madhurima and many more.
The places to visit in lucknow are Bada Imambara, Gomti Nagar, Hazratganj etc.
Hazratganj is the heart of Lucknow, it is the best place to hangout with friends as there are restraunts, Bars, lounge and the most loved place of all age group Sharma Tea shop so please dont forget to visit there.
