Gluten-Free Dining in Portland, Maine: What to Know Before You Order
Finding gluten-free food is easier when a guide tells you more than which menus have a “GF” symbol. Does the business describe its whole operation as gluten-free? Is a gluten-free pasta cooked in separate water? Does a bakery use a dedicated production space? Those are different questions, and the answers can matter when choosing where to eat.
Start with the operator’s own description below, then call or ask staff about your specific needs. Menus, suppliers, hours, and procedures can change. These notes are based on business websites reviewed November 10, 2026; they are not independent kitchen inspections or a promise that a particular meal will meet your needs.

MAIZ: Colombian street food built around corn
For a meal centered on arepas and empanadas, consider MAIZ. The restaurant explains that it makes its arepas and empanadas from corn and says many traditional dishes are naturally gluten-free. Its website does not establish that the entire operation is gluten-free. Ask which dishes meet your needs and how they are prepared, including fillings and sauces. Read MAIZ’s explanation of its food.
The operator’s accessible food page does not clearly confirm the current street address or hours. Check those directly before setting out; older directory listings show different locations.
Orange Bike Brewing: a gluten-free brewery in East Bayside
Orange Bike identifies itself as a dedicated gluten-free facility at 31 Diamond St., Suite D, in Portland. It makes gluten-free beer and says no outside food or drink is permitted inside. Its FAQ also describes a food partnership with its neighbor Bite Into Maine, but the page does not establish today’s food menu or its current preparation arrangements. Contact the brewery before relying on a specific meal or lobster-roll option. Location · Food and facility FAQ
Solo Italiano: ask about pasta preparation
At 100 Commercial St., Solo Italiano’s menu page says gluten-free pasta and dishes are available and invites guests to ask their server. It does not explain the kitchen’s cross-contact procedures on that page. If separate cooking water, utensils, or work surfaces matter to you, ask about those details when booking or before ordering. Menu items may change. See the restaurant’s menus.
DiMillo’s: waterfront dining with a clearly stated limitation
DiMillo’s is a floating restaurant at 25 Long Wharf. It says its menu identifies gluten-free items and dishes that can be modified. It also says food is prepared in shared cooking areas with shared equipment and that it cannot guarantee against cross-contact. That is useful information to weigh before choosing the restaurant, particularly if you need strict avoidance. Ask the team about the specific dish and whether it can meet your needs. Read the restaurant’s allergy information.

It is an option if you are planning to leave Portland for a bakery stop; check the bakery’s current selection and hours directly.

Roots Café, Westbrook
Roots Café says it is 100% gluten-free and offers both sweet and savory food and drinks. Its listed address is 20 School Street in Westbrook. Ask the café about the current menu and any other ingredients you need to avoid. Roots Café
Five questions to ask before you order
If avoiding gluten is medically necessary, describe your needs directly and ask how the particular dish is prepared. The Celiac Disease Foundation’s dining guidance suggests asking about preparation practices as well as ingredients. Useful questions include:
- Is this dish gluten-free as served, or does it need a substitution?
- Are the fryer, grill, cooking water and preparation surfaces shared with gluten-containing foods?
- Can the kitchen use clean cookware and utensils for my order?
- What is in the sauce, marinade, dressing or garnish?
- Has anything changed in the ingredients or preparation since the online menu was last updated?
If staff cannot confirm a preparation method that meets your needs, choose another option. A menu label alone does not tell you how every dish is prepared.
Frequently asked questions
Are there dedicated gluten-free places in Portland, Maine?
Orange Bike describes its brewery as a dedicated gluten-free facility. Ask the business about its current food arrangements and any specific concerns. Nearby Bam Bam Bakery in Falmouth and Roots Café in Westbrook also describe themselves as gluten-free operations.
Does “gluten-free option” mean a restaurant uses a separate kitchen?
Not necessarily. A menu may offer substitutions or individual dishes without having a dedicated kitchen. For example, DiMillo’s explicitly notes that it uses shared cooking areas and equipment. Ask each restaurant how it handles the dish you intend to order.
Can I find gluten-free pasta on the Portland waterfront?
Solo Italiano lists gluten-free pasta among its offerings at 100 Commercial Street. Confirm availability and preparation with the restaurant before visiting.
