Setagaya or Ippudo?
Totally different animals...Ipuddo is designy/sceney, with rich rich pork broth. Setagaya is a casual noodle shop, and you can taste the seaweed/dried scallop in their salt-based broth.
both good, it's personal preference. I LOVED ippudo, but pork broth is just slightly more approachable for the inexperienced....
