If you believe that the decent cuisine of the "Huth" is also present at da moritz "in Italian", you will be disappointed; however, da moritz is a bit more expensive.
The staff is incompetent and especially unable to handle the truffles correctly. As da moritz charges truffles per gram, it basically is a wise idea to use a scale before and after your dish is "truffled-up". However, the waitress failed miserably in every aspect.
Besides, last time I went there (in October 2006), the truffles were shallow indeed. No smell, little flavor. Definitely not worth the money spent.
The interior is up-market, designer-styled and a bit cold. However, as already indicated, the food does not match the looks of da moritz.
da moritz could have been a nice place, if it wasn't for the food: the dishes look special, but their taste is shallow. As for this, da moritz is way too expensive for what it offers, or better said: delivers.
Go there to impress your future mother-in-law, but only if invited.
