I always prefer HWH Rajdhani and SDAH Duronto.. Infact I've booked a return tkt in SDAH Duronto on 26th Aug.. Just coz of timings.. Never ever travelled in sdah rajdhani n don't even have any plan for future :P
Hwh Raj is the numero uno n Sdah Duronto is the 2nd best (for me) ;)
Sdah Duronto has the best food the fish chop is the ultimate one :)
