The best coffee shop I've found in Vegas, and I've spent some time looking. They have coffee-based cocktails (vs alcoholic ones, that is) that are excellent. I've been to a place back in Minneapolis that does this, and the trouble is that they apparently found that bitters and other flavored items are EXPENSIVE, so their "cocktails" are barely flavored. Not so at PublicUs--there is plenty of flavor.
I especially liked the "coffee soda" and the "coffee old-fashioned." I never tried the straight coffee but the staff seemed obsessional enough that I assume confidently that it's great.
