Best Buffet in Delhi?

Best lunch buffet in Delhi/NCR under ₹800–1,500?

Body:
My friend's birthday is on 1st July, and we're planning to go for a lunch buffet since it's the most cost-effective option for our group.

Budget is around ₹800–1,500 per person (discounts/offers included).

Right now we're considering:

• Pirate of Grill, Vasant Kunj (Ambience Mall)
• BBQ Times, Gurugram
• GT Road

Are these good, or are there better options in this budget? Looking for good food and ambience. Personal experiences would be appreciated
