we have eaten at Kona Cafe twice, once for breakfast (Tonga Toast) and once for dinner. Both times the food was great. Our server was a bit slack at breakfast but I suspect because, as a party of 7, she assumed (wrongly) that she would automatically get 18% tip. We only saw her once, when she came to take our breakfast order. A runner (or possibly a different server) brought our drinks and food and we were still waiting for the check 20 minutes after we'd finished eating. I eventually had to ask somebody to go and find her and then she came up , flung the check on the table and tried to run straight off again. I stopped her and told her we wanted to settle immediately. We paid the check in cash and I explained that we would not be leaving the 18% included tip since we didn't feel the service we'd received from her was worthy of that amount and then gave her a look that dared her to argue with me. Needless to say, she didn't. We left just under 8% tip which I still thought was over-generous.
Needless to say, it didn't put us off going back. I am always willing to give somewhere a second chance. When DH and I went for dinner a couple of years ago, both the service and the food were excellent. We are going back in August for dinner and may well give breakfast another try also.
