I'm not sure what the usage of の in this sentence is?
と makes sense to me as in「何でも食い放題と飲み放題」but why is の used here instead?

I couldn't find a definition for this in dictionaries, but I think this の is an emphatic listing particle. It's used between two similar words that describe a quality or state of something. It's typically used between two mimetic words (example), but it can be used with other na-/no-adjectives.
の is used to enumerate verbs and adjectives and 食い放題の飲み放題 enumerates two adjectives: 食い放題 and 飲み放題.
