Something like this?

color[___] = Black;
color[Drink] = Blue;
color[Meat] = Pink;
maxfont = 100;
minfont = 10;
     Style[#1, "FontFamily" -> "Helvetica",
      "FontSize" -> Max[maxfont*#3/Max[sales[[All, 3]]], minfont],
      "FontColor" -> color[#2]
     ] &,
   SortBy[sales, First],

of course you might want to use something smarter for the font sizes,
but that would need more information about what you want to read from
that tag cloud...
