I've always been around the area scouring for a good coffee (there are plenty here) but Tango definitely is at the top of my list.
On top of having amazing coffee, they also have an assortment of gluten/flour free baked goods which I appreciate so much! It's so hard to find baked good that are flour free, and the fact that Tango goes out of their way to bake it and make it fresh every morning and tasty gets my vote.
Of course the coffee and treats are a little bit on the pricier end, but it's great quality.
The staff is so likeable, you walk in and you already feel like you're loved. The atmosphere is comfy like many others had said with the casual sofa chairs and the yellowish lighting. If it's nice, I would recommend sitting outside on the lawn chairs enjoying your coffee while people watching.
It's just a really nice chill place. You can take a date here, study (they have great wifi), your mom, or just come here to relax. It's never too crowded, just enough where you're not the only one and feel bad for leaving when you have to.
