Tastey protein bars??

(Sorry for the double post.. but wanted to try to get more ideas)
So... according to my nutritionist I have to take in 60+ grams of protien aday and I am on a complicated diet (Kind of a diabetic plain, but to much to explain) so my question is to all you is:

What is the best tasting high protien,low sugar bar that you have tried?

I am not looking for one to replace my meals, but a good one for on the go or in emergencies. I have tried Supream Protien and two of them are not bad, but I am all about taste if I am going to put it in my mouth

Thanks!
