On Saturday , I had dinner and drinks at Kumiko 's house with her two friends visiting . We had these things called turban snails , otherwise known as sea snails . They 're the kind with the spiral - shaped , thick , generally rough shells . It was my first time having them , although not my first time seeing them .
