Nanashi Ramen: Shibuya
There is more then just Ichiran Ramen in Shibuya. To be honest I really don't like Ichiran Ramen, I know that might be an unpopular opinion but oh well. I like this place because it's really good and there are tables upstairs you can sit at with a group and downstairs is like a bar setting. The ramen is really good and I love the soup (soup? broth?) that its in.
Before I came to Japan I wasn't a big ramen fan but I think that it took me a while to find the kind I like. I prefer the noodles to be a bit thicker and the soup to be thicker and creamier, which this place does great!
This restaurant is a chain but I haven't seen it around really anywhere else. Its across from the Uniqlo near Shibuya 109. I highly recommend trying it while you're in Japan and if you're with a group.
