If you face difficulty to find places to eat especially with baby, fist option might be family restaurant such as "Jonathan's (ジョナサン)." Before, Jonathan's had a poor image with limited unattractive menus, but recently, they have dramatically changed in a good way!
|Tagliatetelle with Homard and tomato (JPY1,119)|
|French fry (JPY399)|
|Beef steak bowl with foie gras|
|Udon for kids (JPY329)|
This style of restaurants always prepare menu books with photos. So, if you travel to Japan, it could be helpful. Most of all, I'm sure you can find something you want to have among variety of menus!
