Whenever I attend a convention at the World Trade Center (former convention center), I park at the Hilton and grab a cup of Joe at Fortuna. Sometimes the lines are long, but it moves quickly so I'm not too worried about it. Every once in a while I'll grab a Danish with my cup of Joe.
You can also buy glasses of Wine here and on certain days they have FREE Wine tastings. Good stuff.
Will I return? There's no doubt about it.
