Fantastic Okonomiyaki. I arrived at 8pm and was seated 10 minutes later because I was on my own but the queue was long and I imagine most people wait around 30 minutes.
I was handed a menu (with English) in the queue and then a few minutes later I was asked for my order. I chose Ajinoya's mixed okonomiyaki, their speciality. I was sat at the grill, watching the chef work his magic. I had to wait about 10 minutes for my food to be served up on the grill in front of me. I was asked if I wanted mayonnaise, mustard and other toppings - I said yes to everything. It was delicious!
