This is an Indian food stall in the food court of Riviera Casino and Hotel alond the Strip. You will find it easiest if you use the southest entrance of the Hotel, from there you will enter straight to the food court.
They have the usual South Indian snack foods (dosas, uttapam, idli), samosas, a vegetarian plate (thali). And they tasted good (I´ve had a masala dosa, uttapam and idlies), came with coconut chutney, sambar and a third sauce with a little bit of chili.
The next stall serves a veggie burger, but I didn´t ask if the patty is vegan. Anyway it needs to be asked without cheese, my vegetarian spouse had one. There are better veggie burgers on the menu in the same hotel in the Wicked restaurant.
