Time Out says
Almost halfway between the main square and the train station, this is a classic Zagreb restaurant of once state-owned ilk. The food is sturdy and the dishes traditional. In the no-frills, three-room dining interior, you can expect classics such as sarma (sauerkraut stuffed with minced meat), lamb, veal and seafood. Purger, by the way, is local slang for someone born and bred in Zagreb.
