What to do around 4 am in Cleveland?

Hey y’all! I’m a German brewer visiting the states for the first time ever and I will be staying in Cleveland for three days. As I travel partially by Amtrak I will arrive in town on Tuesday the 18th at 4.23 am right after St. Patrick’s Day. Do you have any recommendations for diners (like the typical all day all night ones from the movies lol) or anything else I could do besides just lurking around until everything opens up? Appreciate it!
