Good location, nice ambiance, and decor, quality products, friendly staff; Higher Grounds checks all the boxes! My wife and I checked it out for the first time this evening, and were most impressed. The owner was really nice, and gave us a great deal. Will absolutely revisit, and recommend.

Love this place. Great selection of beverages, from coffee to root beer; plus edibles, tinctures, and pre-rolls. Everything is well organized and easy to explore. I tried the South Pacific tea and it was delicious. Customer service was excellent; Nina and Mark were both friendly, knowledgeable, and genuinely helpful. Looking forward to my next visit.

We're from out of town and thought the concept of this place was intriguing- ended up loving it! Sipped on some delicious hot chocolate at the window side bar area while my husband shopped for some Christmas pre rolls. Life is good here :)

*This is review for the tea not cannabis. Got a Assam ice tea from Higher Grounds. It’s good black tea but I wish the tea flavor is a little stronger. Nevertheless, I enjoy my cup of tea while walking around downtown Portland. Vibrant wall mural. Cannabis section at the back (21+ only). The staff were very nice. Some indoor seats and outdoor seats.
Smoking indoors? The right air purifier eliminates smoke and odor in minutes.
