UK, Ireland / What is the best way to meet a Polish girl in London for a serious relationship? [29]

I am a British, white male who has spent most of my life in Canada but now living in London. I am divorced but never had children and would like to meet a nice Polish girl. I am 47,5'11", 175 pounds, fit, professional, polite, educated and successful.

I do like that Polish culture has a strong focus on family. I am also a practicing Catholic and know that most Polish people are Catholics.

Any suggestions on the best place to meet Polish women in London?
