Zoroastrian dietary traditions in the LA Persian community

The single source ^[1] discusses Parsi Zoroastrian festivals in India but does not address food practices, purity rules, fire-temple offerings, Gahanbar feasts, or restaurant accommodations. No information is available about which restaurants in Los Angeles accommodate Zoroastrian observance, nor any details about how Zoroastrian foodways differ from Muslim Iranian and Indian Parsi traditions. To answer this question, sources would need to cover: (a) specific Zoroastrian dietary laws (e.g., purity requirements, halal vs. non-halal distinctions, restrictions on certain foods); (b) descriptions of fire-temple offerings and Gahanbar seasonal feast menus; (c) a comparison of Zoroastrian, Muslim Iranian, and Indian Parsi food traditions; and (d) a list or directory of LA restaurants that cater to Zoroastrian dietary needs.
