How to Find Dog-Friendly Restaurants and Cafés?

Hi all, how do I know which restaurants, cafés, or areas of shopping malls are dog-friendly? Are there any general rules or signs to look out for?

If anyone has a list of nice pet-friendly eateries, I’d really appreciate it!

I’ve also heard that if dogs are in a stroller in shopping malls, some places might close an eye? Has that been your experience? Would love to hear your tips and recommendations!
