If you are the type to walk a few extra blocks for quality specialty coffee (we are!), Café Tacuba Neustadt is the right spot for you.
They have tasty coffee and handmade cakes from a local baker (happily not a defrosted wholesale version like many cafes).
They also have a small offering of brunch options like acai bowl, avocado toast, and waffles.
It's a 5 min walk into the "Neustadt" neighborhood south of the river, a convenient option if you are staying in a hotel in this area.
