Go find some authentic Chinese/Vietnamese/Indian/etc restaurants that are run by and largely attract those immigrant communities. They tend to be tiny hole-in-the-wall places in strip malls next to nail salons and the like. You'll find they tend to be cash-based even to this day. And the good ones attract plenty of people.
