Be prepared to wait at least 20 minutes. Both my vegetarian ramen and my husband's non-veg ramen were quite salty, so I'd ask for less salt. Vegpicante wasn't spicy at all (and I'm a spice weenie.)
As an American looking for a break from tapas, Koku was perfect. The owners are very welcoming. The picanteramen was right up there with ramen in New York. Especially the kimchi. Highly recommend.
