DIHM (Lajpat Nagar) is way better than Ashok Institute of Hospitality and Tourism Management(Chanakya Puri) for BSc in HHA. DIHM is part of NCHMT and has better faculty and management. Also there are future plans to convert it into university. Placement in DIHM is quite good with Oberoi, Taj, Hilton , Radisson who came previously to recruit. Hope this helps.
