The Scottish Café in Lwów (Lviv) was a meeting place where mathematicians of the Lwów School of Mathematics discussed problems and recorded them in a notebook later published as the Scottish Book.
Notes on verification
Confirmed by multiple independent, high-quality sources including Wikipedia, MacTutor's reproduction of Ulam's own preface, and academic sources, all consistent in details.
