(This venue is closed.) A old spelling system of Indonesia permitted use of the numeral "2" to deal with doubled words. The numeral might appear inline or as superscript; gado-gado, for example, would be rendered "gado2" or as a seeming "gado squared." Under a more recent spelling system the practice has been deprecated, but it is still employed in casual usage.
And now this quirk of spelling has popped up in the Haitian community, too. (Any East Indies-West Indies connection? I can't say.) After an extended closure, this casual restaurant has reopened with a new logo that perhaps is intended to give a boost to franchising opportunities ("coming soon," according to a sign in the window). "Yo Yo Fritaille" is more or less an emphatic way of saying, "here you can find a fried combo of meats and tubers." "Delicious" is implicit.
