I just checked the link. So it's basically a free place (no cover or membership fee), with free wifi, and free food, without any catch? Sounds a little too good to be true...
We also give free bootcamps and lectures here, as well as have occasional guest speakers (Chef, CoreOS, etc).
The only real downside is sometimes all the available seats/tables get occupied by people working on stuff, so it helps to get here when we open (10am).
