Fare is little bit high, but if you are travelling in Shatabdi Express you have to pay more. Food provided is some how ok. It takes approx 7 hours. It's a morning train. They will provide 1 bottle water bottle, may be news paper. Snacks and lunch.
I boarded the train at 3 pm and we were totally hungry so pantry facility were mind blowing. Firstly we got tea and snacks and at night at around 7 got dinner as chicken and veg-paneer. Serving was nice gave us all the stuffs. We took photos as well.
There were two different looks of Kolkata. Say, South Kolkata and North Kolkata. South Kolkata is modern. On the other side North Kolkata is old aged with old buildings. Park street is at the centre. During, March to September, it is hot and humid otherwise pleasant in other months. It is seeped in history and culture but lacks upkeep and progress. Bengali food is wonderful.
