Ramen and other casual restaurants appropriate for teens (Seattle)

Hello,
#1 Looking for outstanding ramen to take my ramen aficionado teen. Preferably not too far from airport (we are traveling from airport to Port Angeles area), so perhaps somewhere along the route? (If possible)
#2 Casual restaurant (also for teen) with outstanding oysters, or something teens would like (ie: not too fancy/stuffy) , Korean bbq, Chinese, American (no pizza/Italian, no Mexican)- same geographic location. Thank you!!
