On evening of new year I visited this place with my family and we throughly enjoyed the monument and arrangements done for welcoming year 2018. . A cab from Lahore would be easy way to access. It has a reasonably sized park around it with food outlets. One can go to top by lift to enjoy view of area.
There is a hotel at level one which serves dinner. Advance booking is advised to avoid wait as space is limited. Weekends would be busier than weekdays.
There are few shops that serve snack (Gol Gappas etc) and you can sit and chat around. It's a good replica of Eiffel Tower and nice place for photography (wedding etc).
It is a great place to spend the evening with family & friends.
