Nice location. Great service. Roomy with wifi. What's the problem? The coffee.
If you're going to open a coffee shop you should look at a place like Cartel as a model. Roast your own beans or at least buy fresh coffee and serve it by a pour over to get the best quality. If you have overlyl roasted coffee in a container I can do that at home just fine.
It's probably fine for the Starbuck's customer. You know the one who likes hot brown sugar water and foo foo's it up with caramel, whipping cream etc.
