Not really.

It’s actually the English “Caesar”. The founder’s of the OG bar and recipe are Italian but Tijuana has always been a bilingual place so instead of the Italian Cesare or the Spanish César the official name is just the English version of the name.

Now, the Latin <ˈkae̯sar> is absolutely the origin of the Italian Cesare with such a well documented evolution that for our purposes it is the same name but with a modernized pronunciation. In Italy (& Mexico’s César) the name made a huge comeback in the XX century but we cannot deny that is Julius (and their tyrannical parasocial followers) who made his cogname as famous as it is.

Extra dato curioso para los lenguados 👅 vivo en Tijuana y nadie dice “seizar”, literal cada restaurancito que tiene la misma receta escriben el nombre anglosajón en sus respectivos menús. Definitivamente vas a toparte con quienes la conocen exclusivamente como ensalada César pero sólo porque no conocen la historia (story, not history) y/o porque lo ven como una chicanda/pochismo. But that’s not here or there.
