I used to go to Wagamama every time I get the chance. In a short holiday in London I went to the Tower Hill twice with husband and kid. The children menu is a very good value (plus pencils and papers to entertain the kids and special chopsticks). On my first visit I had my favorite dish: yaki udon. Good but with only one prawn - I slightly complained to the manager who immediately apologies.
On the second visit, I had Pad thai noodles - very good (with TWO prawns this time!!). The manager recognised us and offered us a free dessert for the whole family. I think it was a really nice gesture that was highly appreciated.
I will keep Wagamama in my favorite list of restaurant!
