It is unfortunate that I have to update my review from 5 stars to 1 star. I have recommended Kona Grill to many of my friends and out of town visitors. I returned to Kona Grill this past Friday to enjoy their happy hour once again. We were sat immediately outside on the patio. We were ignored for over 10 minutes.. no one came up and even asked us if we wanted water (in the Vegas summer weather) and there was at least one server around helping other tables. We just walked out and mentioned why were walking out to two staff members. Neither of them tried to do anything to keep our business. We ended up at another restaurant in Fashion Show and loved our experience at the alternate spot. We will have to take Kona Grill off of our list of favorite spots to enjoy due to the non-existent service.
