Also, seeing as you are in Cambridge, see my other note about my favorite restaurant (not takeaway!) pipasha.
For renus, tell them you come from "John from Citrix/Science Park", and if he hasn't forgotten of me (I doubt, since I ordered more than 50 meals from him in the last year) he will treat you nice. 
My favourite restautant(well pub) is the wrestlers, best Thai food I have ever encountered.
I know Citrix, and you probably know Autonomy HP where I work for my sins. I'll mention you when I go for a take out, thanks!
Oh, I know wrestlers. A number of people at Citrix used to go there on Wednesdays, they also claimed it was the best thai food in Cambridge, but I've always walked further down to pipasha myself. If wrestlers had been serving the last time I was around, I wouldn't have sprained my ankle, as we arrived a bit too late and they didn't serve food then, so I called pipasha and they were still serving, we kept walking and bang... nearly broke my foot, but the guys at pipasha were massively helpful and made sure I felt well.
btw, no need to say my name to get a good service from renus, but it may help just to start. He doesn't work lunch time, so aim your orders for 6 plus
