I took two half day tours with anirban while I was in Kolkata. He is polite and a well informed guide. He had information about every places in the city. I had lots of questions even about places that we drove past, he was able to answer both. He was also able to show me the off-beat old kolkata which i was keen on. I was happy with the tour that he put together. I would reccomend him to friends and family who are visiting Kolkata.
