This pretty much sums it up: biggest yakisoba in Seattle for $5.95.
(I'm usually opposed to "teriyaki" joints since you don't even cook teriyaki like that in Japan, but we were hungry and waiting for a bus.) Yakisoba is sort of a festival food in Japan - some dude in a festival booth cooks up noodles on a big teppan grill over high heat, all greasy and shiny (or you can go to an okonomiyaki restaurant and cook yourself - v. fun). So by no means it can be glorified, but I sometimes love it the same way I love good hot corn dogs few times a year.
Some yakisoba's are posers, using chow mein noodles and the like, with "teriyaki" sauce (no teriyaki sauce for yakisoba!). The one you get at University Teriyaki is pretty good as far as the fast food place goes. It's made with yakisoba noodles, and it has the correct kind of seasoning.
The thing which impressed us is its sheer SIZE. The plate is about a foot wide, and the dish fills it. If you have small appetite it could easily feed three people. And it's under $6. So if you lose all your money one day, go there to fill up.
Like most teriyaki joints this place is run by Korean folks (so I'd stick with Korean and "Japanese" dishes), so their jjigae (hot pot stew) is a good deal as well, and they bring it out bubbling hot (they bring your food but you bus). Very flavorful. If you add tofu/meat and some veggies to it, you could probably eat it with rice for a couple of days. Most of their dishes are under $6 before tax. A good resource for a starving student, or when you want to explore new territories with Korean food for dirt cheap.
