Knock-off name or not, it’s good that supposed restaurant has Kosher & Jewish pride.
In Paris, some “Kosher” restaurants are ditching Hechsheirim because (among other reasons) the snobby (non-Jewish) Parisians consider restaurants with Kosher supervision sub-standard.
Additionally, if a restaurant is truly Kosher, having the word Kosher makes it easier to locate for newcomers. So it’s a win-win unless the Halal Guys decide to sue for brand infringement, which doesn’t seem likely to me.
