So just back and I had lots of Veltliner and less beer. The Schweizerhaus is huge, but I learned you need a reservation on a Saturday night, so no beer was had. Did not make it to 1516, but heard it was good from a colleague.
Had dinner at 7Stern, it was excellent.
They have a beer vending machine for bottle purchases in their entry way, if you just want to grab one to try. The dunkles was my favorite.
