UK: how easy have you found vegan no nuts eating out?

I’m allergic to all nuts, eggs and dairy, I’m just wondering how accommodating you’ve found eating out? I have been vegan in the past but relied on nuts for pestos and fake cheeses and chocolates (I’m allergic to pine nuts too even though they’re seeds lol) so a vegan option previously sufficed

When my allergies arose i started just being veggie and avoiding nuts and eggs but now I’m also allergic to milk I’m a little worried about eating out

If anyone has a similar list of allergies please let me know any chains you’ve found or good experiences you’ve had- i know lots in this group will have much worse allergies and more of them to consider but I travel a lot for work and I’m a little overwhelmed by how ill manage this
