Sindhoor is without a doubt the best curry I have ever eaten. Since I ate there the first time a few months ago I now eat there at least twice a month. We have introduced many friends to the restaurant too who also think it's fantastic. They also offer takeaway which is a bonus.
Because the restaurant is small, service may take longer than usual on a Friday and Saturday but I don't care waiting at all when I know what I'll be eating. Because it's South Indian there aren't the usual curry dishes we see but again that's great because the taste is so much more authentic and flavoursome.
The one thing it'll also do is ruin other curries for you. I loved other curry houses in Manchester but now none of them compare to Sindhoor.
