Is Kadarka open?

Is this what you're asking about?

There's a note on their FB page that states (using google translate):

You may have noticed that there has been a slight change in our opening hours.
We will be CLOSED on Sundays, but don't be discouraged, because you don't have to give up the delicious Hungarian wines Margitka is waiting for you outside on Margitsziget until 22:00 even on Sundays.

Biztosan észrevettétek már, hogy kis változás történt a nyitvatartásunkban.
Vasárnaponként ZÁRVA leszünk, de ne csüggedjetek, mert nem kell lemondanotok ezért a finom magyar borokról a Margitka nagy szeretettel vár kint benneteket a Margitszigeten vasárnap is este 22 óráig.

They should be open at 4:00 (16:00) today.

Thanks so much, Kathy.

You're welcome! Enjoy the wine! :O)

I hope you guys are waving on the way. 50/50 chance you walk past my living room window.

We had a great time at Kadarka. Sorry, no waving.

P

Glad you enjoyed.
A favorite. But there are a lot of places to visit in town.

As we have discovered!
