Substance Diner

Pleasantly surprised!Grabbed a bite before a comedy show at Screwbean Brewing. We may not have opted for vegan, but glad we got to try it.We ordered the Spicy Fricken Sandwich which is a seitan version of a chicken sandwich. It has great flavor with a nice texture. The substantial burger was also well seasoned. Very reminiscent of a burger, while i wouldn't necessarily say the chicken tasted as such.Fries were amazing! So fresh and juicy.Id be happy to dine here again.

The Barby's Roast Peace and Spicy Fricken Chickn sandwiches are both great. Wish I had come with more of an appetite because the Sonoran Dog looked really good too. It's always great to find a fully vegan menu in Tucson but even better when they have unique menu items and you can bring them into Screwbean next door to eat. Will definitely be back for more.

Vegetarian comfort food out of a small old time camping trailer parked outside a brewery?Need anymore be said? Okay, it's a review so, yes.The Barby's Roast Peace Sandwich, thin sliced scratch made seitan stuffed in a sesame bun, with onions and vegan cheese, is incredibly satisfying.The Veganer Schnitzel, scratch-made seitan thin cut and breaded, is another winner.Finally, the French fries. I rarely eat fries and have never written about fries. Fries are pretty much fries. Not much to say about fries. Well, I'm wrong. These may have been the best fries I've ever had. The balance between heft, crunch, and texture elevates these fries to gourmet level for me. I never thought I would say that about fries.Tucson surprises me yet again in a good way.

Enjoyed this spot today. Ordered a few items on the menu. The grilled cheese was really cheezy. The bread is what made it stand out. Same for the Roast Peace sandwich. Not stingy at all the protein at all. Very filling and flavorful. A must try in Tucson

This is definitely my first time going here and I was totally surprised. I was surprised first that I found the place because they're right behind the brewery. You can order food from the brewery and they will get it to you, but you have to find it and they will deliver it to the restaurant as well. The vegan comfort food was such a delicious and amazingly tasty food that I will definitely be back. The gentleman that was there was so friendly and helpful with ordering for my first time. if you are looking for a great plant-based getaway from the norm definitely visit here. Even if you're not vegan, you will love this place!

We were happy to find this gem in Tucson, AZThe seitan was one of my favorites I've hadDelicious food and cute ambience Loved the retro look of the trailer!Check them out!

ALL vegan menu and food truck located right outside the Screwbean brewing co. Location,-The food we ordered was fantastic, one of the best Seitan spicy crispy chickun sandwiches I've had, big huge crispy patty, finely sliced lettuce, and yummy fluffy bun. Also had the Philly cheese steak sandwich that was hearty and packed full, along with the crispy lightly breaded fried pickles with homemade ranch, yum! Finally, we also thoroughly enjoyed the chocolate-peanut butter milk shake that was knock our socks off delicious!!! :PService was friendly, kind, and very prompt, with every item made to order! Nice blocked off petite outdoor table sitting area with quiet surroundings. I truly can't wait to come back to this little gem! :D

Great vegan food. The turkey sandwich and chicken nuggets were absolutely amazing and all at a very reasonable price.

Great vegan diner food, we can always rely on Substance for the good stuff. Best vegan Sonoran dogs we've ever found. Thick diner fries that are seasoned great, and great vegan ranch. We love their new spot behind Screwbean Brewery, I hope it serves them well! We always go out of our way to find Substance Diner. Yum!

The food is amazing very delicious! The cooks are very nice as well. So sad they aren't behind the coffee place anymore.
