Cantina OK! describes itself as "a place where you can drink one of a kind, one in a million, once in a lifetime spirits". I can't put it better than that, except to add that it has been named as one of the 50 best bars in the whole world for its extremely rare collection of mescals. Prepare for a unique experience, even by Sydney standards! Set in a disused one-car garage, there's just enough space for 2 bartenders to mix amazing drinks while happy customers pile outside into the laneway. Unbeatable.
