Someone sent me a link to a new ramen shop in DC which has an amazingly simple menu: Ramen, Dumplings, and 5 sides and some pretty cool decor. Just based on the pictures and descriptions of the food, I'd love to try this place, but unfortunately it's 1500 miles away from me. It sounds like you may have quite a wait for the food, 2-3 hours based on this article.
A segment of the above link:
Situated above The Pug, Toki Underground is a little jewel box of a restaurant. A lot of thought has been put into the interior, which is a funky mash-up of skateboards, colorful graffiti and cutely subversive Japanese toys. The narrow space is ringed with approximately two dozen counter seats, an open kitchen in the back and a shared bathroom sink so small you might miss it if you're not paying attention. Clever details -- like the blinking pachinko games embedded into the bar and dessert served in panda-shaped bento boxes -- add a twist of whimsy to the otherwise edgy atmosphere.
As for the food, Toki Underground definitely hits more than it misses. The menu is short and sweet, focusing on a selection of ramen and dumplings. Toki Underground doesn't exactly serve traditional Japanese ramen, but Chef Erik Bruner-Yang's renditions are enjoyable nonetheless. The menu features five different kinds of ramen ($10 for a bowl), four made with a tonkotsu (pork bone) broth and one vegetarian broth made with shitake mushrooms and kombu (seaweed).
I'm a pretty simple guy and I don't like to wait 3 hours for a meal for anything really, but this place just sounds cool. If any of my DC area readers try this place, let me know and send pics!
