It is one of the most well maintained trains at the MB-DLI route. I've travelled almost 20-30 times in this train in all the classes of travel. If you've booked it in AC Chair Car, you have the following menu available.
Bread cutlet/omelette
Vegetarian biryani (rice).
Tea.
Tomato...
more... soup.
Casual snacks (Chips, soft drinks, biscuit etc)
while only the last on the list is served in the crowded 2S.
The train is clean, as I said, well maintained, well prioritized.
