Is there a noun for an additional portion of food that you take / ask for, when you are done with what you have been served, but still want more.
I am almost done with my plate, can I have an ________ (addition?)?

You can ask for a refill, which is more appropriate. "Can I have a refill? I'm almost done with the noodles!"
"Serve", "helping" or "seconds" (in order from most formal to least formal)
As in:
("seconds", in this case, is short for "second helping")
When referring to drinks one generally asks for a "refill", but with solid food we ask for a second serve/helping
In the example sentence I would just use "another".
I am almost done with my plate, can I have another?
In more general terms, I agree with Smoke's answer.
