We stayed at the Hyatt much of December but didn't go to Japengo until near the end of our visit. We had no reservation but went in early. We sat at a table inside the sushi bar area and enjoyed the experience. I agree with a few others that the timing of the delivery of the food is slow, but, quite frankly, we were in Hawaii to enjoy the pace. We did, also, have a few drinks before the sushi was delivered. That said, the rolls were well prepared and very tasty. One sushi chef was a pleasure to watch and listen to. He was obviously not shy. All in all, this was a good evening for us. Some friends had reservations later and we stopped by their table and understand why people would make a reservation and sit out on the end of the patio. What a fantastic view! When we return, we will prepare for a longer dinner outside.
