I love Phoenix, and I love supporting local Cleveland businesses!
Phoenix has the nicest baristas ever. My friend and I work here often, and we comment often on how interesting and kind they are. It's a nice space to work in - fairly quiet with good varieties of indie music playing in the background. There's a diverse crowd that comes. This is a place where I routinely see Asian Americans come to study and work.
I usually have supervisory or business meetings here too. The environment works for both work and play. Free wifi too.
They have great chairs, good decor, and a community feel here. There are often crayon-drawings of the community or the baristas.
As for coffee, it's pretty ok. They have a great selection of teas. My favorite is Japanese Sencha, and I'm fairly happy with their selection of green teas. Their cookies are great snacks - go for the oatmeal cookie ones with cranberries... it's perfect.
Overall, I enjoy doing work here and I've gotten quite used to it!
