KOS is one of my frequent cafes. Everything on their menu is probably good, have yet to get something I didn't like. It is a really big space, surprisingly big, and they wisely separate a laptop/work side from a laptop-free side. The line is usually out the door, which is technically a good sign, but can make for a longer wait as the staff isn't always the most attentive. But the food is worth the wait, and the coffee (their own roast) is exceptional! My one actual issue is the $10 credit card minimum, but oh well
