The cost of an all-you-can-eat buffet at Barbeque Nation outlets across New Delhi typically ranges between ₹800 and ₹1,400 per person, depending on whether you choose a weekday lunch, a weekday dinner, or a peak weekend service slot. Special celebratory dates, festive seasons, or promotional seafood and barbecue festivals can introduce minor pricing variations. Diners frequently check digital restaurant reservation applications or official brand portals to secure promotional package discounts, pre-paid vouchers, or special group celebration rates ahead of their visit.
