I've been here at least 5 times this year, since trying it for the first time in January. The restaurant is small (and a little too cozy) but the service is great and very polite.
As usual, of downtown restaurants, there is no parking unless you park on a side street. During the lunch hour, if you get there past 12, you can expect to wait in line outside for around 20 minutes before getting seated. It's quite small inside, probably seats around 25 people.
The soup is here pretty good. My personal favorite is the Spicy Tantan. Though the name suggests spicy, there's not a lot of kick which is perfect for me. I also love the soft boiled egg they serve with some of their ramen choices. Their karaage is also well seasoned and fried to a light crisp. The portion sizes are great for a quick lunch, but for those with a bigger appetite, you should definitely order more noodles.
