When i want a noodle place that's quick and cheap, I love going to Zyng. It's a no-frills type build-your-own-meal restaurant. You can pop in and sit at the window and people watch, or grab something quick to go.
I'm a picky eater so the choose-your-own-veggies style suits me well. You pick from a selections of noodles, sauces and protein (meat or veg) then grab a bowl and pick your own vegetables. They fry it up quick and serve it hot. I don't find the portion size too small. No need to pile your plate high and stuff your gut. If i'm really hungry i can inhale the whole bowl. But usually i split it into two meals and have the leftovers the next day. I love the Fiery Teriaki sauce!
Overall a great, cheap noodle spot!
