Hey, if you can find good food somewhere, regardless of time, Go for it. There was one time I was coming off a shift for a project at 6am. I had been up literally for 20 hours to help implement it. On the way to the subway station to head home, I walked past a 24h Burger King... and at the time, I realized I hadn't had any food for more than 12 hours. So walked in and ordered two whoppers (minus the pickles and mayo). When I got home, added some marbled cheddar and shoved one into the microwave and just devoured it. No one I know would eat a whopper (or any hamburger) at 7am, but hey, it was pretty good and better than anything I could make in a semi-comatose state.

Or the time I arrived at HKG at 6am with my next flight being several hours away... I forget the name of the restaurant (Coral Cafe or something like that? It's at one end of the airport on an elevated food court)... anyway, they had 干炒牛河 (cantonese rice noodles w/beef... not CKT although similar) that they just started plating... it's not traditionally a breakfast meal... but it felt like a good meal to me (after being on a plane for 15 hours).

My point being, if you see it, and you're in the mood for it, regardless of the time, why not.
