We went to origin with a groupon. Though the food was good the service needs a lot of improvement. We don't go out to Indian food very often because it is soooooo overpriced in vegas and we often make our own instead. We tried it because of the groupon. The service was disorganized and not the friendliest. I think only one guy actually smiled. Our child has a lactose allergy and the waiter told us they could separate out the cheese naan. They forgot. There was confusion about where they put the groupon and our bill had to be redone. Nothing too big a deal but the lack of friendly attentive service was surprising considering the expense. The food itself was some of the best we have had in vegas. There are not that many good Indian places here. Don't know if I would go back considering the prices and mediocre service. BTW if a decent Indian place ever opened with significantly lower prices like they have in other cities, we would be there EVERY week. I don't know whats up with the jacked up prices for Indian food. We end up going out for Malaysian or Aftican food as an alternative that is more affordable.
Also, I am married to an Indian and so we know our Indian food.
