I use culinary agents for food industry jobs. I also highly recommend going in person to drop your resume off. Even if they’re not publicly hiring they could be looking for people, just to see. If you don’t want to go in person, email with a resume, a cover letter, and offer to stage (depending on what work you’re looking for) Try your luck
Also look at places that are not explicitly labeled as restaurants like hotels, cafe’s, grocery stores that have delis/bakeries.
Hope you find what you’re looking for !
