Read Vanessa T.‘s review of Avogadro’s Number on Yelp🥗 Dietary Options & Customization at Avogadros Number Fort Collins
One reason Avogadro’s Number in Fort Collins receives consistent praise is its commitment to catering to a variety of diets without excluding anyone. Although it’s not strictly a vegetarian restaurant, the menu heavily features plant-based dishes, and reviewers often commend its adaptability
The Tempeh Burger and Veggie Steak Sub provide satisfying, meat-free options. Additionally, items like the falafel gyro and breakfast burrito can be customized with dairy-free or meat-free alternatives, and the kitchen staff is typically very accommodating with substitutions.
“It’s not a vegan restaurant, but the tempeh options are super solid. They’ll usually make swaps if you ask—like avocado instead of cheese.”
🧀 Vegetarian vs. Vegan
While vegetarian food at Avogadros Number Fort Collins is abundant and well-loved, vegan diners might find the choices more limited. Items like the Reuben or Joe’s Sandwich include cheese or creamy dressings by default, and not all can be subbed easily.
