At the suggestion of our friends, we stopped at Island Lava Java for a quick cup of coffee and a behemoth cinnamon roll on our way to Volcano National Park. Fantastic Kona coffee and the cinnamon roll was ample for the two of us to share. Prices were reasonable - our total bill was about $11 for two cups of coffee and the cinnamon roll. We were paying $10 for two cups of coffee at our resort.
We would have been happy to stay and eat in. The place was packed early on a Friday morning and we wanted to get on our way. We didn't have to wait long in line for our to-go items though. A cruise ship had just anchored, so keep this in mind when venturing down that there may be an influx of people with your same plans.
