"It’s a rite of passage to complete a wintertime Green Lake lap by warming your hands with a bland flat white here. But the secret to getting the most out of this waterview location is up a hidden staircase by the restrooms. There, you’ll find a serene rooftop overlooking the lake, complete with comfy chairs and table umbrellas. It's also close enough to the wifi router for optimal al fresco email-answering." - Aimee Rizzo
