If I were to go on space alone I would give this South Indian restaurant 4 stars. It reminds me of some really authentic Southern restaurants from India. Kudos on the great service and the authenticity of South Indian-style steel dishes and flatware.
Aside from that, the lunch buffet is pretty solid although not the best I've ever had. The servers do their best to take orders and hand out hot dosas as if there was a fire.
If I could give the owners some personal feedback, I'd recommend an extra emphasis on presentation and dessert to breathe some life into their spread. (I'd love to see that Kesari Rava that makes the rounds at Sarvanaa).
