Here's a whole bunch of info from a previous post (including this link to a blog all about the food there) that I found really helpful..
Here's a copy and paste from an earlier thread on this:

Thanks everyone for enjoying our foods! We will be winding down(not as many visitors frequent the park) after sept. 16 but still open for business until the second week of November...Yes, there are plans for a more permanent establishment all-year round in the near future. Huaraches, pupusas, tacos, ceviches and anything else you may favor we will be happy to provide. Meantime, we are in the process of constructing a website redhooklatino.com and\or redhooklatino.org which will be hopefully up and running by late fall where we will provide info. dates, times, events, (even recipes) for your convenience. Special thanks to J. Slab and his wonderful blog. His coverage of our events and food surpasses any article written about us thus far. Last, thank you all for your enthusiastic support and positive comments.
