Came here on a Tuesday to see the Marcel exhibit. Got a membership so 10% off at Theory, but even without that it’s legit prices for Portland. Their cheeseburger tasted char broiled and had a great GF bun available. Kids said the grilled cheese and pizza were great too. Lastly, got a vegan Santa fe bowl, which was really hearty and filling. Beautiful, relaxing atmosphere with tons of space. Now that we’re members we’ll definitely come back and just chill in here while the kids explore. Thanks for the great spot, OMSI!

Came here with our family. Not the most intuitive set up. You have to grab a menu and then find where to place your order. We say outside. The patio could use some tidying up. Most of the food was tasty and a good value but the mini beef tacos did not taste very good at all, bitter aftertaste, and we not worth the price considering the portion given. We liked the chips, roast beef sandwich, and tuna sandwich. Would do again, just avoid the tacos.

Gross cold pizza. Premade crust looks nothing like what is shown in pictures or on display. Witnessed them drop a rolling pin on the floor and then pick it up and put it on the counter with the food. I would avoid.

My son forced me to walk a extra mile to eat here. He remembered the oizza being real good. I have to admit the views are amazing but we agreed the pizza wasnt that good and we didn’t even finish it.

Calling this “pizza” is a lie. So disappointing.

Very disorganized. Extremely long wait for food and had to go back to inquire and then they had to redo order. Disappointing with a $75 plus lunch. Overpriced.

Really good chicken strips and the fries are super different than any that I’ve ever had. The staff is super friendly.

The good! Great location for OMSI visitors .The bad! No half sandwich’s. Ordered the Roast beef, he asked toasted or not, I said toasted, they toasted the whole sandwich, not just the bread. It no seasoning, really just a bland flavor. The chips were really good though. Expensive a little, for $14 a sandwich and a drink.

Waited half an hour for a salad that had bread too hard to eat, rubber for cheese and so much vinaigrette it tasted like pure vinegar. Also a “grilled cheese sandwich” that was barely melted on the corner and otherwise a lukewarm sandwich with solid cheese slices layered in between. The rest of our family seemed to enjoy the mac & cheese and their pizza. We realized after that we were also charged full price despite my husband showing our membership card. They don’t give you a receipt, so not like that’s something we could get fixed either. Not overly impressed. Giving 2 stars since they managed not to mess up all of the meals. For my daughter and I alone, it would be 1 star.
