Within KCLS, there are two public libraries that have maker spaces (AFAIK): Bellevue, Federal Way.
PS this is not meant to be confrontational, would love it if there were more maker spaces in libraries (when have asked in the past, the usual answer is that they do not have enough space for it).
I'm willing to bet that the libraries near the person you're talking to have all but maybe a cafe. I mean, I've never seen a library in the US that didn't have internet access and a place to meet and that weren't nonprofit.
There are lots of libraries with cafes, maker spaces, and more. Seattle is one.
If yours doesn't, this is your wake-up call to get involved with your local library. Stop waiting for someone else to do things.
