So I thought I had logged into my account...apparently I had not so there are now 2 reviews that are identical. Sorry about that!
We got into Zurich in the morning and by the time we got to the hotel to drop off luggage and figure out where we were it was time to find something for an early lunch. We read about Sternen Grill in the inflight magazine on the way over so we set off to find it and see how good the brats actually were. A ride on the #4 tram took us to the Opera House area and we looked around for the lines we read about....but nothing stood out. After discovering the square and lake we literally walked right into Sternen Grill...right across from one of the Tram stations. The lack of long lines was evident when we discovered we were there a half an hour before they opened at 10:30 am. They have some tables with umbrellas between their building and the neighboring one so we had a seat and waited patiently for them to open.
I'm used to the way brats are served in the States so we were surprised when we received 4 brats wrapped in paper, a loaf of bread and a few containers of mustard. The entire meal was hot, fresh and REALLY good, The bread was crusty and soft inside and the mustard was pretty spicy, but not so much that you couldn't enjoy it. The brats were item #1 on the menu and were excellent! grilled just right so they had a crisp casing, hot inside and very juicy. Combine this with a couple of cold beers and you have a great meal.
The restaurant isn't well marked but it's definitely worth finding and trying out. If you're by the Opera House in Zurich look for Sternen Grill, defiantly a good place to eat.
