Sunday lunch at Fendel's
Fendel's is a really nice "Weinhaus" with a very good restaurant in Rüdesheim-Eibingen. In summer they have a great patio outside with a view down to the rest of the city and the Rhine.
We went there on Sunday for lunch but since we went late, it wasn't as crowded any more as during regular lunch time. Lucky us - we were able to choose our table and the food was just amazing (and not pricy at all!).
If you come and visit, also try the "St. Hildegard-Kräutersuppe" - a creamy soup with fresh herbs à la St. Hildegard (the St. Hildegard nunnery is just up the hill). Extremely delicious!
