Hi,
Thanks for submitting your designs.
I'm liking the font quite a bit, and the brightness/happiness of #15 made me smile, but I'm afraid I would get tired of it over time, and it seems a little too much "Welcome to the Good Morning Cafe"-a little small town-ish.
I'm also not in love with the coffee bean shape. I like the idea of combining a cup shape with a coffee bean, but it's a bit too much of the coffee theme in the logo.
I like the blue color in entries 11 and 15.
And I might like one word in the blue and another in the grey of #10.
Thanks again for submitting your designs!
Andrew
