There are lots and lots of different versions - some with diced; mine is with chicken parts although the recipe's at home. It's otherwise pretty similar. I've seen a number of regular supermarkets selling the nice brand of Paprika from Hungray - it says Szeged on it (that is the town where they grow the peppers). There is sweet paprika and hot paprika - I prefer the sweet and it's definitely what you'd get in a resaturant. Oh, and paprika should be stored in the refrigerator.
Yum! and yes, Budapest is my favorite foreign place.
