MH uses the ITC Green Lounge in Delhi. I don't believe there is a shower.

MH191 is a sub 5 hour red-eye. Last I know, the service is supper after takeoff, and no breakfast (I mean, it's a sub 5 hour flight).

And MH doesn't do turn down service in J, like on the longer QR flights, and especially not on this flight. No amenity kits, and no duvets or seat covers either if I remember correctly.
