Healthy Portland Restaurant Plates That Don’t Feel Like a Bummer | Eater Portland

"It might feel tempting to call the Buckman vegan cafe Fermenter “simple” — it only has a few items on its menu, and the restaurant has very few seats — but each dish is wildly intricate, involving house-fermented pickles and krauts and Oregon-grown quinoa. The spicy cabbage and tempeh bowl, which comes with house black bean tempeh, spicy cabbage, and miso, is a highlight." - Brooke Jackson-Glidden

Great place to hangout with a group. We got hazy IPA - peeling eyes and a feared or loved. Both the beers were great. Smoked almonds were great too. Very simplistic interior with great options for house made beers. Walkable distance from a lot of great restaurants nearby! Outside food is also allowed here.

•August 2024• from the ex head brewer of Cascade comes his own place. With that said, don’t come in expecting sours. The beers were pretty good. The highlight for me was the blonde coffee stout. We came in the afternoon and by the evening it was packed with families and kids. Not really my jam. Definitely not your typical brewery vibe. I was told it’s supposed to be more welcoming for everyone. I’m not a fan of everyone but if that’s your thing you’ll love it here.

Excellent beer. Love that it isn’t too strong. The Bags Out of the Cat is a delicious hazy. Lovely aesthetic- Studio McGee meets a modern Potterybarn. The whole ambience is sophisticated, relaxed, calming. The perfect hangout and gathering spot. Don’t come too hungry;)

The review by John Bedette is not true. The staff did not pick up or yell at the child. The staff were kindly trying to keep the child from hurting himself, he told the child to be careful around a sign that could have fallen on him if he touched it, while the parent was neglectfully letting the child roam the venue unattended and unmonitored. The staff at Commensal is impeccable, friendly, informative when asked. The vibe is chill but sophisticated and so are the beers!

Mike and Morgan are two of the best dudes you’ll ever meet. Go get a beer or five with them at the bar, talk about life, become friends. Whatever hazy is on tap and the session IPAs are always out of control. One of the best places to hang in Portland.

Kind bartender. Smooth, clean, open vibe. 3 phenomenal beers (during our first visit). As beer lovers from Milwaukee, we were very impressed with our experience at Commensal Fermentation!

The beer was good and they had a great pizza pop-up! Cool space with picnic tables, good people. Excited to try the other beers.

Dropped in after dinner across the street. Complete remodel from the previous brewery ~ classy modern livingroom vibe that makes a great place to chill & sip. Fireplace too. Beer is tasty and by the history, they enjoy a good rotation of styles. Service ~ welcoming & friendly! Easy to talk with and courteous to thank you when you leave. Awesome relaxing drinking spot for the neighborhood.

Commensal Fermentation was a great stop on our last trip to Portland! During many of our visits there we try to fit in stops at breweries if we can and Commensal was one of stops. The beer is excellent here! The lagers and lighter beers are quite good! I got a witbier by the name of Horses Held. This beer had elements going on that I love with herbal characteristics, clove, lemon, fruity and breadiness. The taproom is nice looking too with it's clean, sleek look that it has going on. Definitely a satisfying stop and a brewery I definitely recommend if you're visiting. I would love to get ahold of more of those lighter beers!

Cozy spot near Migration Brewing with a more refined vibe. "Commensal" means something like synergy or symbiois, and the friendly owners explained they want it be a space where people chat and make connections. On this cold winter day, it was a wonderful place to sit by the fire in cushy chairs and catch up with my good friend. The beer was impressive - a short list for now, but the hazy was one of the best I've had, similar to the ones I loved at the departed Mumford Brewing in L.A. There was plenty of creamy lactose, but it was still crisp and hoppy. I wish them all luck with this space!

I love the ambiance of this place. Clean and cozy. Minimalist but not bleak, white and devoid of warmth. The 2 tenders at the front were extremely kind and chill. We stumbled in not really knowing what this place was all about and we had a nice conversation with the tall gentleman with reddish hair at the front. Nice wine and beer selection. The pizza smelled sooo good. Would've gotten some if we were not waiting for a table over at EEM.

Super chill spot with a beautiful interior--great vibe all around. The beer list is legit, and it's clear they actually care about brewing well-balanced stuff, not just flooding the menu with hazies. Big fan of the crispy beers and especially the Black IPA, which are hard to find done right. Also love that they regularly host popups--always something good to eat while sipping. Solid place to hang.

Fast and friendly service. Brews were fresh and tasty. Will hit this spot every time I travel to Portland. Shot out to Brewer Mike, super knowledgeable brew master. Looking forward to what he brings to the industry!

Great beer! I have tried most of their beers, their lighter beers are fresh, the hazy was real good. The place is upscaled nicely, they did an excellent job creating a fine place to enjoy fruits of their craft.
