Hey everyone,
I am planning to move to Hungary to start a business in there, I have an interior and architecture design company in Iran. I want to do the same in there. I wounder is market  good in there?
Also I have experience in cafe and bistro business as well and I can work in that category to.( opening a small cafe and opening an interior design company together.)
can anyone give me advise about both of them ?

Have you been to Hungary before? More inportantly do you even speak Hungarian?

No I never been there and have no idea how to speak Hungarian as well. I heard that its a difficult language. but I can use translator !!! :)

most important thing for me is , better to open a cafe or interior design company?
