I've heard amazing things about Sona, so my husband and I decided to give it a shot. From the outside, it looks horrid, but we were brave and entered.
1. The atmosphere was fine. Nothing too special, but miles better than how it looks from the outside.
2. The service was excellent, and the owner came out to ask about our meal while we ate (not in an obtrusive way).
3. The food didn't impress. I couldn't even tell you what we ate because both dishes had basically the same flavor. We are both food lovers, and the only reason we finished our meals was out of politeness. The food didn't taste BAD, but it wasn't good enough to actually make us want to continue eating.
Admittedly, my husband and I are not huge fans of Indian food, so maybe an Indian food lover would feel much differently about this restaurant, but we were not impressed at all, so we won't be returning. I'm not sure what all the rave reviews are about.

UPDATE: All of the good stuff I said above stands, but I'd like to alter the negative.
We recently went to a Meetup that met at Sona. At the Meetup, the chef created four vegan dishes for everyone to share, and through trying them, I discovered what I don't like about Indian food: curry. I love curry in Thai food, but apparently I dislike Indian curry, because every non-curry dish he brought out was a big hit with me. I especially loved the saag and vindaloo.
The rice is also great!
I'm glad we returned for the Meetup, because this restaurant is actually a gem. I'm about to visit now!
