I can't imagine a trip to Roppongi and not stopping into Ippudo. We live in the neighborhood, and eat here regularly - even after trying many other ramen places. It is clean, delicious, and the staff are so patient with our kids. (Not so common in Tokyo's tiny restaurants.) They offer their menu in Japanese and English - so its a great choice for those who don't speak Japanese. I highly, highly, highly recommend this place. And don't leave without trying the gyoza.
