Controversial opinion, I know... I am not a big fan of Da Crack. I can't quite put my finger on it but I think it's a combination of their location (annoying parking lot, no seating, you order at a window), the lines, and the food being okay to good but not great.
If they were at, say, Puka Dog's location on the first floor of Brennecke's across from Poipu Beach Park, I might feel a bit differently. When Rafael's truck was still operating, they were often over at Salt Pond for lunch. I really enjoyed those tacos despite the food not being as good as other options - even say Island Taco's over in Waimea. The convenience factor and being able to just walk from my spot on the beach to the parking lot won out over driving out to get something and coming back with it.
