I've been going to Toyama for 6-7 years now. Used to go weekly when I lived closer. For the price and service it can't be beat.
Around $6 for a typical standard dinner and ready within 2-3 minutes.
Shrimp sauce is the best of any Japanese restaurant I've found. Sweet but not too heavy. Always have more food than I can finish. Not much has changed over the years, that's probably why I still stop in if I'm in the area.
