I LOVE Zubrowka. We have a polish restaurant across the street that serves the best crispy duck. We were there 2 weeks ago & an older lady tried to order her Zubrowka on the rocks (a big no no) & the polish waiter tried to stop her....she insisted.
The wait staff is very particular about how their vodka is served...you get a chilled shot or a martini...on the rocks is very bad form.
I like it very much too.
I think it's the best on the rocks, mixed with apple juice.
We call such a drink "apple pie" :-)
I prefer Russian vodka on the rocks though I've had Russians chid me for adding ice also.
(Polish Vodka 'Pravda' is very good also).
