I have been on a serious Ippudo marathon lately. I think I have been 3 times in the last 2 weeks... and each time with groups from 6-10 people! It's no joke! The weather has made it easy to eat that fatty and delicious soup. People have been going crazy for ramen and the wait is still the normal 2.5 hours on most nights!
My favourite ramen on the menu right now is the Karaka Kogashi Miso Ramen. It's a combination of slightly sweet and spicy taste and not as heavy as the Akamaru tonkotsu broth. It's limited and will only be on the menu till February, probably end of February I'm hoping. So run and try it before it's gone!
