Prices are well above average in all aspects since you have to add a cover charge of EUR 2,20 in any case; however, you get three kinds of bread and decent spreads in exchange.
Every dish is decent at Huth, my favourites definitely being the "geröstete Kalbsleber mit Erdäpfelpürree" and the "Faschierte Laberl mit Erdäpfelpürree und kleinem Salat" as well as the "Erdäpfel-Vogersalat mit Speckkrusterl und Kernöl" as starter.
Expect to pay EUR 18,00 to 22,00 per person, including drinks and tip, if you aim low. If you go for the whole 9 yards (starter, entree, main course, dessert and wine), EUR 40,00 per person are easily spent at Huth.
The staff is genuine Vienna-style, meaning: the staff is the boss, and you are not.
If you want to try/taste original Vienna cuisine at a very high level and want to experience genuine Viennese "hospitality", go to Huth. Now!
Outside seating available; the Italian offset of the Huth (i.e. "da moritz") is right across the street; however, "da moritz" was disappointing to me on three out of four occasions (see separate review), so you might want to stick to Huth.
