This train starts in the night at Mumbai. So, one can get into it after the usual chores are done and rest. It reaches Bangalore around 10 Pm. So, that too makes it convenient to travel home after the peak traffic hours and sleep peacefully.
Having travelled in Sleeper, 3 AC and 2 AC, it offers what Indian Railways offers in every other express train. Nothing exceptional or outstanding. Pune's Vadapav, Lonavla's chikki, Dal vada of Dharmavaram are a must try.
Food is decent, if you are unable to get from home before boarding the train. Since it contains pantry, there is continuous movement of refreshments and snacks prepared freshly. So, there wont be any dearth of food for foodies :)
Bedding, toilets were decent. We cannot expect 5-star type in Indian Railways! So, it was what was expected.
