It's pretty genuine and the food is good. They serve Ethiopian/Eritrean food. Family who run it are Eritrean. It's worth checking out the coffee as well, they serve it in clay jug and little cups you get in Ethiopia.
Been to the Kabalash as well, tbh the food wasn't great. Haven't been to Bataba. There was a Ghanian place in Govanhill that closed during COVID.
