I couple years ago I bought one of these for Mother's day. I live in the US and sent this to my mom in India. I was really quite nervous because I wasn't sure if the gift would reach her, or if they would honor the voucher and I didn't know anything about the food. But after looking around I decided to get this voucher along with some other gifts.
My parents were confused about my silly gift! I did pester them to go use it and when they went, they were very pleasantly surprised about how wonderful their service and food was. They were treated like VIPs with the voucher just because of their wonderful service. MY parents have pretty high standards so that says a lot about this establishment. I was happy that my parents had a great time.
This restaurant is a chain so people might have different experiences at different locations. As for the price, it actually looks extremely affordable to me! But restaurant prices are much more expensive in the US than India so maybe I just don't know. However if you're looking for a unique gift for someone in India, there aren't many gift vouchers options for India and Mainland China is very good about redeeming the vouchers. There are very little restrictions except the expiry date which really shouldn't exist for a voucher.
