I have just come back from one of my jolly trips to London: I was a bit worried about what to eat, in light of recent discoveries... But I discovered a
VEGETARIAN FAST FOOD CHAIN!!!!!: Maoz Vegetarian
There are two branches of
Maoz Vegetarian in Soho, London. Apparently they are pan-european Dutch chain, with branches in many countries (though I've never heard of them before

) - there's a location guide on the website. They serve falafel, fried aubergine, hummous, chunky chips (that's fries, for the Americans

) and as much salad and sauce as you can pile on top of your pitta bread....

So, erm, any town planners or council representatives on this site? Plan for these!
There is also
Hummus Bros in Soho (who get advertised on the banners on here sometimes). They're not a franchise chain, but they should be! They do some really interesting hummus orientated dishes (and lush mint lemonade

)

There are
Bagel Factory outlets at most of the stations: these give you a "create your own bagel" option, so it's easy to get a vegan bagel. They can be routinely persuaded to make a Portobello Melt without the cheese
