I was in Munich earlier this week. Wish I had known about Tantris (we could have done it on expense account), but we did pretty well with our two days.
First night our collegaues took us for "traditional Bavarian specialties" at Spatenhaus across from the Opera. The food was quite rich, but definitely delivered on a typical German meal with beer. Not sure it is any better than other traditional German options, but it delivered on what we looking for.
Second night we had a really great dinner at Sevenfish on GartnerPlatz. Very inventive selections and the seafood dishes had great flavors. I would definitely recommend this place.
