I really dig Mod. As a local I use it to mainly really get serious on a project I've been putting off and/or having a peaceful but stylish place to meet with partners and clients. It's not perfectly quiet but easily better than a public place where people may not be as mindful of common space. There are meeting rooms to seclude yourself but it's also fun to be in a new type of crossroads for PHX.
And the cartel coffee is great!
