I tried the following which were still open in November so are presumably open all winter. They are all within walking distance from the clinic so no need to depend on the very limited bus service (which also stops absurdly early – in winter even before dinner time (???)). Apparently, there is also a clinic shuttle, but I never felt the need to investigate its usefulness.
If, like me, you are only going to eat cake once during your stay, let it be here: Café Deicheck (if you are going to eat cake, it has to be worth the sugar content ….). Their homemade cakes all look gorgeous, and I know by experience that they have great coffeeand a good selection of teas as well.
Another good café is Bäckerei Siercks. And of course there is a café in the clinic too. I did not try their cakes either, but they looked good and homemade.
Vietnamese (I think ….) restaurant Asia Mei, not as spicy as one would hope, but still the tastiest food on the peninsula. I went there several times, and remembered it well from when I was here on a photography course five years ago. Th’ey don’t have a website but are located on the square just by the boardwalk leading to the main beach.
There are several Italian restaurants, but I only tried one: Buongiorno, very close to the clinic. I did not try any of the meat dishes but their fish- and seafood dishes were very good.
SPO Fischhaus – tried their “Fischbrötchen” several times, and their pasta with giant shrimp once – very good.
If you are after “Fischbrötchen” there is also the “Räucherei” next to Rewe supermarket by Bahnhof Süd.
Tamatsu – for if you want to to really treat yourself. Had my 70th birthday dinner there. Modern food with more than a little Asian flair. Delicious.
And finally, GOSH, just by the boardwalk to the main beach. An institution in Sankt Peter-Ording – I have by now eaten there many times. Cozy atmosphere, an outdoor area, Fischbrötchen to be bought outside and various fish- and seafood dishes to be ordered inside. A bar for coffee and drinks.
Beware of gastronomy in more far-off places. Many of them are closed, although in true German IT-resistant fashion, they don’t bother to mention that fact on their website. For example, at the Eidersperrwerk, there are two eateries which both have left giant signs up pointing towards them, they both pretend on their website to be open, but they are not.
