Yes! First review. Which isn't too hard if today is opening day.
I'm not the biggest coffee snob, but I do enjoy lattes and iced coffee. On this occasion, I went with the latte. I was first in line (and immediately after, 3-4 people were behind me--yes!! I didn't have to wait). At 3.85+tax, it was a fair price, given the amount of skill it takes to make a proper latte. My only complaint is that they use Square (which I dislike), so I paid in cash and dropped change into the tip jar.
There are plenty of tables up by the storefront and in the back that each seat 2-4 people. There's also bar-style seating around the espresso machines so you can watch them make your drink. I didn't see any outlets, but I admit I wasn't actively looking for one anyway. Plenty of people were there on their laptops doing work (free wifi!). A few minutes later, the barista came by with my latte and a small glass of water on a tray. I immediately felt like a hipster coffee snob. It was smooth, delicious and well-made.
Having gone to some of the famous coffee roasters/shops (Stumptown in Portland, Philz in SF), I'd say Rising Star is as good as it gets in Cleveland.
