Yama is the best sushi in Vienna, and very good for anywhere. I have been going to Yama for years and it has been consistently excellent. The sushi and sashimi are among the best I have ever had. Clean, fresh, neat, well prepared, occasionally imaginative, always delicious. The service is wonderful and the miso excellent.
Outside the sushi and sashimi the restaurant is good, but many of the dishes are too sweet. My wife, who foolishly doesn't like sushi, has trouble finding a good meal here. I would love to find more options for her, so I could have the sushi more often. But, if you want sushi or sashimi, this is the very best place around. The prices are reasonable, the service wonderful, and the fish the freshest in town.
The a la carte prices are fine, but the sushi dinner or deluxe are real bargains. This is a standard for me, better than all but the most expensive of other options, and much better than anything else in town.
