I don't buy a lot of his observations. It seems to me that he is making the exception the rule. For example, his argument that the strip mall would have cheaper foods is sound, but that those cheap food emporiums would be adventurous and try to do more to distinguish themselves culinarily is dubious.
His generalization of Thai and Vietnamese as well as Pakistani versus Indian is also dubious. There are differentiations between cuisines and his assumptions that they are equivalent is ignorant at best and jingoistic at worst.
