A few days ago my lovely fiancee called me at 4am from New York City where she was attending a bachelorette party. She explained there a lot of "niche" (gimmick) bars there. She was calling from one where all the drinks are served in coffee mugs.

When I open my bar, all drinks will be served in spill-proof sippy cups. The bartender will pour in the ingredients, add the sippy lid, shake, and serve.

The bar's name, of course: Oopsie
