Sorry, this is just not true. Jaleo is in Crystal City.
There are a tonne of lunch options. Crystal City is also adjacent to DCA. So from a travel and logistics perspective, it's a good option since there are a number of hotels there that are used to hosting conferences.
GWU boasted the Wikimania conference a few years back. If we had friends at AU, that would be another strong contender for an academic host.
What was the participant count from LA? That might open up a myriad of options that the Library crowd wouldn't think about but could readily fit.
