I liked this place, and I really wanted to like their Reuben.
The staff was very friendly, and I am partial to handwritten menus, which they had. It stretched the entire restaurant length and had tons of variety, everything from breakfast to desserts. They even offered a service where they would prep food and then you could take it home and cook it yourself. They tried really hard.
They also had the best children's menu I saw on any of the Hawaiian islands, bar none.
The Reuben was a disappointment. The bread was very dry and not overly rye. I couldn't taste the cheese or the sauerkraut, though the beef itself was very good. I thought that they had put some sort of mustard on the sandwich, but further investigation revealed that the mustard flavor was part of whatever the dressing was.
The cole slaw that I got with my sandwich was far better than the sandwich itself. The slaw had the standard ingredients plus raisins, which IMHO was a stroke of genius. It was unexpected, but delightfully so. The lemonade (which I shared with my fellow reviewer) was good, but too sweet and not lemony enough for me. I probably wouldn't have paid $2.50 for it.
On the whole, I wished we had discovered the place sooner on our trip so we could have eaten there more times...skipping the Reuben, natch.
