This place has the best coffee and espresso in the Glendale area, period. If that's all you're looking for then it's a 5 star cafe. Coffee prices are reasonable too.
The only reason it's a 4/5 for me is that their food, while great, is slightly over-priced. That being said, I don't mind spending a little extra to support a locally owned place.
Service is excellent and the owner is nice to chat with. Overall, this is my go-to cafe in Glendale.
