Yes it's available, but no it's not going to be anything better than an average/good bowl.
Tei An has a passable miso ramen and it's probably the best option we have in the immediate area.
A ramen counter popped up a few weeks ago at the Super H-Mart food court. The tonkotsu bowl I've tried has been acceptable (nice and chewy chashu despite a one dimensional broth and too soft noodles), but I haven't run through the whole menu yet.
If it really has to be North Dallas, Sushi Robata does have some ramen dishes, but not something I'd recommend nor have high expectations given that it's not their specialty. Mr. Wok in East Plano is ok too. Ino also has ramen but I haven't been there in years. Hope that gets you started.

I know Mr. Wok is a Chinese/Taiwanese restaurant, but it is true that their menu did have ramen, at least it'd been that way since I'd first heard about them in 2004. I can see why they'd take it off considering people pretty much never order it.
Thanks for that tip on private social - how much is a bowl?
