321 Ellsworth has vegetarian options, but none seem to be vegan-compatible. Ca Cafe in Palo Alto will have lasagna and didn't seem amenable to modification. Cetrella Bistro is meat-only. Viognier in San Mateo has vegetarian, but not vegan options. I'll try calling Arcadia next week, but, at this point, I think the best bet would be to go to Parcel 104, stick my head in, see if I can eat anything, and, if not, I'll go off to another restaurant.
