You can get food in the Manas Maozigendri Ecotourism Society camps . All meals are served here and the cuisine is local. The local cuisine uses rice and fresh vegetables. Pork, chicken and fish are common, as the Bodos traditionally are non-vegetarians. While you are there do try the favourite drink of the Bodos - a rice-wine named 'Zu Mai'. The forest department guest houses also provide food at reasonable rates.
