I actually use OLA cabs more often for weekend and office purposes. I have used their OLA shuttle from Ballykhal to Hudco, which is also good. They charge really for what you need and no need to bargain. The cabs always have drinking water, air conditioning, wifi and relaxing music. With OLA prime you can enjoy media content on their tab which is provided in the cab. The ride experience are also good the drivers are professional at their work. I use paytm so payment is also very smooth. Overall a very smart way to travel in cab and the services are great in Kolkata and its outskirts.
