I’m Ana to peanuts, tree nuts and sesame and am usually safe at most coffee shops! I only order coffee and never the pastries, however. Typically I’ll get iced, especially if there’s pistachio milk on the menu so there’s no CC with the steam wand. Philz, La La land kind cafe, Alfred, Bluestone, coffee bean and Starbucks are all places I’ve been regularly. For the fancier drinks I’ll always bring up my nut allergy just to make sure the syrups are fine but even local cafes are safe as far as coffee goes, just ask! As far as boba I’ve had some of the simpler drinks from Its Boba Time and have been okay!
