I'm not sure if there's an option to reserve here, but everytime I've come there is about a 10-15 minute wait-- I guess a testament to how good the food really is! If you're not super hungry, you might want to consider sharing with a friend, as the portions are quite nice and filling. The ratio of noodle-meat-broth-veggie is done well, something that many ramen restaurants often can't achieve. The charsiu is meat is soft and fatty (but in the good way) and I was actually wishing for more pieces of just that! The interior of the restaurant is nothing super special (which is fine), and you'll likely eat and dash, not somewhere that I'd stay for more time to hang out.
