It depends on the usecase. If you're querying for something local like a restaurant or a store, google wins by orders of magnitude. If you're researching, duckduckgo is fine. Duckduckgo doesn't really compare to Kagi though.
What's wrong with DDG and local searches? I find it exceedingly good, especially with the country selector being so up and front. It's very easy to search for those kinds of things in other places, for example to plan a trip.
Kagi for me is a no-no. I mostly browse on temporary containers, and also have Firefox delete cookies on close. A search engine that requires me to be signed in would be a massive pain to use.
When I try your query I only get a bunch of local German stuff (including a map with restaurants).
I admit, I don't even know what Kiel is so I can't validate the results but despite them being in Germany (and my search having had the country selector set to UK), it looks pretty good.
If I search something more generic like "all you can eat sushi" I get a neat map with a few restaurants that do that, plus a bunch of TripAdvisor and other directory and blog posts exactly about that, all local.
If I try your query again, setting the country to Germany, I get https://yummy-kiel.de/ as the first result, a map with top-three restaurants as the second, and again, a bunch of directories and blogs with all you can eat Kiel.
With all respect, there’s not a lot of restaurants around here ) comparing to i.e. Hamburg. A couple of steak houses, some locals, 4-5 asian food and the Brunswik, which is always busy. There’s also Kiellinie, but it’s mostly a seasonal thing. Though there’s a lot of folks around sipping cocktails with ice in winter, crazy. Love this city.
