Sierichs Biergarten

In the location's words:

In the middle of Hamburg's Stadtpark, directly on the Stadtparksee lake with a view of the planetarium - an after-work beer could hardly be more beautiful. Sierich's beer garden is the perfect place to take a deep breath, enjoy a beer and watch the sun set over the planetarium. Pure Hamburg flair.

It's open depending on the weather - just check the traffic lights on the website: Green means go! 🟢
