I can’t directly answer your question, but I can give you a tip on how to find out. Right now I work for big giant lab company that has workers all night and there is one place that’s open until something like 4am, just because it’s just down the street from the lab. When I worked at the hospital before working here, there was another place that was also open until 4am because they were very close to two hospitals. If you have a big hospital near you, call around… chances are there’s a pizza/sub type place open after midnight that delivers.
