Not my favorite ramen bar but definitely unique and worth going to. Main selling point is their hours; they're open super late so that's great. The ramen is tasty and they have a great selection of appetizers, sides, and desserts.
The bad part is always the wait. There's almost always a line, especially at night. The service is a tad slow due since it's always busy. But the service you do get is decent.
The prices($11-$15)are also a tad higher than Monta ($7-$8)/Fukumimi($9-$10). But you are paying for quality ramen so I think it is worth it.
