Sumo Ramen was a pretty good experience- I had never been to a place that sold solely ramen until I went there.
The server was very nice and friendly. He made suggestions for appetizers. We decided on octopus balls. I've never had those either until then. They were pretty good!
The ramen is also very good. It was a bit blend for me but they do have sauces on the table for extra taste to it.
