OK, this list of summer drinks assembled by The Oregonian sounds truly evil and something to definitely try. It's obvious these establishments take their summer drinks very seriously. Personally, I want to try the B-Side soda at Sahagun. Not just because it sounds great, but I then have an excuse to eat more of her chocolate. If you haven't tried it you must.
Shops mentioned include:
Northwest
Sahagun
Elephants
Downtown
Give Pizza a Chance
The Sugar Cube
Spella Café
Northeast
Por Que No?
RX Roadside Juice Bar
Southeast

Trebol also serves agua frescas. Read more about them here.
