I've been to 3 branches so far (Akihabara, Shibuya and now Shinbashi) and they are very consistent in terms of food quality. Surprisingly / distressingly the same can be said about ambiance.

First off, the food here is good low brow spaghetti, as basic as it can be with complimentary size upgrades and then paid upgrades for the massive upgrades. Pricing is absolutely in line with what you get, in fact probably lower than what you might expect.

Ambiance however is straight up scary. In this, as in the other 2 locations I've been to, the building housing the restaurant looked to be on its last legs, you trek down rickety stairs that are so narrow that passing somebody is a feat in gymnastics. Inside the shop itself is so cramped that you get to know the people sitting one table over very well. In earthquake country, you are very much gambling that this heavenly pasta will be consumed allowing you to climb up from the scary, dank basement before the next 7.0 quake hits.
