For lunch today, we went to Jangara Ramen in Harajuku at the recommendation of my colleague Li. In his mail to me, he said, "...you'll be in pork fat heaven! Some say it's the best in Tokyo, and I can't imagine better tasting ramen."
OMG, he wasn't kidding. Jangara specializes in Kyushu-style ramen. I don't know if I can characterize the differences, but the broth is pork-based (vs. miso or shoyo-based) was perhaps a bit richer than I'm used to, and the pork was cut thick with a luscious cap of fat. The boiled egg on top was soft cooked, and the whole thing was topped with cod roe (lovely). The pickled greens and crushed garlic on the table made the bowl even better. For more, here's Rameniac's description of the style.
You could order one of a couple styles of ramen, each with options A-H which defined the toppings (everything, no egg, etc.) We also had nice gyoza to go with. They had English menus, and the staff was quick and helpful. I slurped down my bowl and ate what the kids' didn't finish from theirs. I was stuffed to the point of pain, but I couldn't stop eating. I'm still silly with the thought of the stuff.
Jangara is a small chain in Tokyo; there are actually two at this location on Omote-sando Dori, located on two floors. They are about a block from the Harajuku JR train station. They were apparently voted best ramen in Tokyo in 2003. I must find who won this year.
