The ramen thread seems bloated & unrelated, so starting a new thread for this.
I have to add a glowing recommendation for U:Don in the University district, it's a great food experience. Currently they have a seasonal special: tan tan udon that is IMO fabulous. Of course I like me some spicy tan tan (think Aloha Ramen).
Noodles created fresh in front of you, choice of sauce/soup, cold/hot plus additions: green onion, shaved ginger, panko crumbs. They also have a selection of tempura if you want it; it's just OK.
Under $10 for a large order. There's always a long line of Japanese students at lunch <hint>.
Ambience, meh...it's the U district. I take it to go, it is cold after all.
