There are many Bamboo Sushi locations around Portland. Bamboo is our favorite place for sushi, where we had our first date and even where Steven proposed. If sushi is your thing, we highly recommend Bamboo.
Depending on how much adventuring you are up for, Multnomah Falls is a quick and beautiful drive from downtown. There is a short walk up to the top and a visitors center at the bottom. We are lucky enough to still have the falls to enjoy after the fires of 2017.
Voodoo is the well known donut spot in town thanks to Portlandia. While it is great for the experience, we recommend Blue Star Donuts, Pips, or Coco's for a tastier treat.
Be prepared to wait in line! If the line is too long and you aren't huge into trying the flavors, go ahead and walk up to the refrigerator case at the front and grab a few pints to go!
