At the risk of being insulted for posting an honest and negative review -- check out the replies to negative reviews below -- here goes:
The decor inside is very nice. The metal plates are an authentic touch, but I don't enjoy eating off them. Middle class privilege, I guess.
The lunch buffet food was decent enough the two times I've eaten here. Some items were much more spicy than I like in that particular dish, some much less spicy than I like. I'm a culturally European white guy, so I may not have a clue how these things are supposed to taste, but I eat at Indian buffets a couple times a month and I know what makes me happy. And I'm the guy eating the lunch.
The service is...well...there isn't any service, really. Long (L----O----N----G) wait to be seated, long wait to pay the check, long wait for food to be filled on the buffet (whole lunch with no naan bread though I asked for it at the beginning of the meal...) and customers have to go get their own utensils. It is not unlike eating from a vending machine, except that vending machines are pretty quick. The last time I came I walked out after waiting to be seated for way (W----A----Y) too long (two other parties there suggested I just sit down and start eating, but that didn't feel right to me). I drove over to Maharana and had a nice lunch and -- importantly -- felt like a valued guest.
Maybe the owner of OM will put on a couple more staff members, or perhaps he'll just write a reply insulting my personal life. We'll see.
