Going to the Delhi book fair today. Any advice?

Hey guys. Going to the book fair in Delhi today in the afternoon for the first time. I've been in the city for half a year now but this would be my first time in any large event. I was wondering if someone more experienced could give any advice when going. Not looking for anything specifically or even to buy, would just like to browse and look around. I'm mainly a fantasy and sci fi reader so if you guys know where stalls related to my interests are, please let me know. I'm also wondering if specific publishers or imprints of publishers like Orbit, Tor, Gollancz etc. have stalls.
