I have never tried okonomi before today and now I am a devotee!
I went for lunch with a couple of friends today. Be forewarned, the lunch portions are HUGE. My friend and I shared the seafood deluxe okonomi and it was delicious and extremely filling. Huge shrimp, calamari, really generous servings in this dish. Our other friend had the chicken teriyaki and it was a very full plate of large pieces of chicken on a bed of rice.
This place is not very big and quite popular. Quick, efficient service, though and very affordable for the large portions. I want to go back and try the non-deluxe pancakes because maybe that deluxe pancake was extra-large in comparison. I'll let you know!
