How do mixed race couples get treated different than same race white couples here?

Im a veteran considering moving here from California I’m not fully white and my girl is Mexican. We drive Japanese cars. Will I get funny looks and have a hard time making friends based on this in the Shavano/ Hollywood areas? Downtown? I’m sure there is racism naturally and historically but what form does it take there from first hand experience? Is there a substantial presence of Mexicans in the more expensive areas? Or will we be extreme outliers?
