Diamonds Coffee Shoppe 
This shop is in a colorful old industrial building and has a really fun retro motif. The rating is low, though, because the staff has been consistently cold if not rude on multiple visits. That expectation is established. The coffee was OK. They have snacks and food but it isn't notably good or interesting. The place is fairly small and uses the large back hall as extra space. During the winter, that hall can be uncomfortably warm. Not recommended.
