I recently came across Still Tasty, and I give it two thumbs up. The site provides a reference for how long food will stay both safe and, yes, tasty. In doing so, it strikes a nice balance between providing official information and realism.
Yet where the site really shines is in answering those underrated questions like, Is it OK to put hot food directly into the fridge? Another one is whether or not you need to refrigerate open ketchup and mustard bottles. Answer: Heck no.
And then there’s my personal favorite: Is bottled water safe to drink after its expiration date? Two words: Hell yes.
