ASTERA

ASTERA's menu is described as entirely vegan, consistent across its own website, a Portland Dining Month listing, and a press review. The kitchen prepares no animal products by design, making this the core of the concept. No certification, such as the Vegan Society Trademark, is mentioned, and no information about shared equipment or cross-contact from non-vegan ingredients, such as honey, is available, so the tier is A rather than A+.

As a fully vegan restaurant, every dish is also vegetarian by definition. The Portland Dining Month listing explicitly notes vegetarian options. No cross-contact risk from non-vegetarian ingredients exists because the kitchen is 100% plant-based.

The restaurant is fully vegan, so no dairy ingredients are used. Multiple sources confirm that the menu is entirely vegan. Cross-contact issues or shared equipment with dairy are not discussed, but the structural absence of dairy in a vegan kitchen places the restaurant at Tier A.

A fully vegan restaurant uses no eggs in any dish, so egg-free diners are safe by design. No dedicated kitchen or cross-contact mitigations are described, but the ingredient base is inherently free of eggs.

The restaurant is fully vegan. No shellfish is used in any dish. Although a vegan kitchen sometimes uses seaweed-based 'caviar' as a substitute, no crustacean or mollusc ingredients are present.

The Portland Dining Month page says gluten-free options are available and that modified menus can be requested in the restaurant. The menu description includes a smoked cashew ricotta fritter and seaweed caviar, but pasta or bread may appear. No marked menu, no dedicated fryer or separate prep area is mentioned, and the venue's own website gives no allergen detail. A diner with coeliac disease should contact the kitchen ahead and speak to staff about cross-contact risk.

The Portland Dining Month page states gluten-free options are available, and the menu includes some typically low-FODMAP-friendly whole plant foods (beet, cashew, rice, vegetables), but there is no explicit mention of low-FODMAP accommodation, FODMAP training, or a marked menu. This is thin positive signal only; call ahead to confirm.
