Since being forced onto a low sodium diet by a medical condition I've found that I can eat Indian and other South Asian food without a problem but that Chinese and other East Asian food is off limits. Nepalese is something in between with some dishes too salty. I expect the same would be true of Tangra: I would have to order the "Indian" dishes, and my wife would be able to order Chinese dishes she doesn't get to enjoy as often as she would like.
