I don't know if there is a plain vanilla flavor or not, as I ordered a pineapple dole whip, but yeah is was just pineapple flavored soft serve ice cream. There was a citrus one too and then they had them as floats too with the juice added, but what I had was a soft serve in a cup and it was very very good! A very generous portion too and it melted way faster than I could eat it without getting brain freeze.
