I'm not a big meat eater, but my DH loves Biergarten. They have a bunch of really yummy veg-friendly options: spaetzle (German baked mac & cheese), warm potato salad, potato & leek soup, smothered cabbages, potato dumplings, different salads, homemade breads, & REALLY tasty desserts. I think you'll be pleased with what you can find there.
