Answer for What are the most accepted credit cards in Hungary?

Credit cards, especially Visa, MasterCard and American Express, are widely accepted in Hungary, and you’ll be able to use them at many restaurants, shops, hotels, car-rental firms, travel agencies and petrol stations.
They are not usually accepted at museums, supermarkets, or train and bus stations.  Many banks, including K&H and Posta-Bank (represented at post offices nation-wide), give cash advances on major credit cards.
