Beef Stroganoff in San Diego
I went to pomegranate for my birthday this year and my mother ordered the stroganoff and I was pretty stunned how good it was! I havent had many stroganoffs but this one took the cake. But I think in experience - as a whole - this restaurant only puts out REALLY good food.
You might want to check out Rei do Gado or Brasil for Brazilian stroganoff which is very popular there too.
Pomegranate on El Cajon Blvd in North Park has Stroganoff - both Beef and Vegetarian on the menu.
I haven't had the stroganoff, but others I have been with ordered it and enjoyed it very much. There were a couple of threads about the place a year or two ago and it generally got very positive comments.
