When I was working in the office a couple of weeks back, I went out to lunch with the Ops team to this fantastic place called Maoz. The key to this vegetarian Dutch chain of take-away joints (this one was the first in London), is the freshness and variety of salads on offer. Its core menu item is the fresh falafel that you see being formed and cooked right as you order it, served up in a fresh brown or white wrap to which you can load on a ridiculous heaping of differently dressed salads.

Details: Maoz
Found on: 43 Old Compton Street, Soho
Highlights: Offers a huge variety of salads, fresh falafel, pretty good chips (for the UK), fresh juices and a busy vibe.
Room for improvement: Store gets pretty busy at lunch-time and more seating could be offered (but a perpetual problem in the UK)
The Kua Rating: 7 out of 10
