La Haven Coffee is new, and still working out a few things, but this little shop is otherwise just about ideal to work from. Staff not only welcomes and encourages it, but also actively solicits suggestions from customers - they truly are trying to build the business around customer needs.
Coffee selection is about typical, although they do come up with a few specials most days. They also have a couple of teas to choose from. The menu is currently pretty small, just a handful of pastries, although they are exceptionally good.
What La Haven absolutely excels at is comfort. Seating is more than plentiful, so much so that the room seems empty sometimes even when mostly full. (The previous tenants of the space, a restaurant/bar, couldn't comfortably fit a 1/4 what La Haven can in the same space.) The background music is just that - background - so having a good conversation with someone is easy. You may not have access to an outlet from every seat, but the seating is so plentiful that if you wait five minutes, you'll probably have an outlet seat open up.
Two other big plusses at La Haven: 1) Internet speed is very good, and the upload speed is amazing - almost as fast as the download speed; and 2) the hours. On Michigan Avenue near the Museum Campus and Soldier Field but still in a residential neighborhood, La Haven isn't restricted by the Loop business cycle, and stays open until a reasonable 9:00 PM.
Energetic, it's not, but it's work-friendly in spades. If you're looking for a true neighborhood shop, this one will suit you well.
