Available on request, No marked menu but staff will accommodate. Quality varies by who is working that shift.

Vegan options are listed as available by one aggregator source, but a community reviewer explicitly cautioned that the venue 'is okay if there are no vegans' in the group, suggesting vegan accommodation is inconsistent and limited.

Not appropriate, Documented unsafe, multiple negative reports, or refuses to accommodate. Surfaced to warn rather than recommend.

Shellfish is a core menu component across multiple spaces — La Llotja (seafood restaurant), the Oyster Bar, and the Beer and Preserves Bar all feature shellfish prominently — making this venue structurally inappropriate for shellfish-allergic diners.
