Hello friends, I finally discovered an oriya restaurant in gurgaon. This place is called "Maachh Bhaat" (which means fish-rice) and serves authentic yummy oriya food cooked traditional style.
My personal favorite: Rohu Dalma thali and fish meal.
For those interested: Maachh Bhaat , Opposite gate no. 2 Maruti Udyog Vihar Factory, Gurgaon. Next time I go, I will get some pics!!
