I was speaking to an Indian guy about this just a few days ago. he told me that these restaurants cater almost exclusively to pre-arranged tour bus groups that are composed almost entirely of Indian tourists. I believe him because I have no reason not to when he says that they are not at all interested in walk-in traffic an this is why none of them advertise or even seem at all concerned about whether or not there are a dozen other Indian restaurants in the same neighborhood.

There is one Indian across the river.... ONE. So this suggests to me that the Indian tourists must be hiding somewhere over on this side lol . I don't really notice very many Indian tourists in Da Nang at all.
