The Open Guide to Cambridge

Pakistani restaurant on Mill Road, possibly better described as a cafe, since the interweb suggests it doesn't have much seating. Also does takeaway, and I think delivery. Also sells sweets.

It's recommended as a halal venue by the University of Cambridge Islamic Society. zabihah.com says the owners are Muslim, and no alcohol is served.

Cambridge vegans and vegetarians pass on a rumour that it's good for vegans, but at this point this is third-hand information so I wouldn't rely on it too heavily.
