Last time I was out at bars in NYC it was 4am and I believe this is still the case. DC is 3am, as is Hawaii, West Virginia, Indiana, and some places in Illinois. Parts of Alaska are apparently 5am and Louisiana has no official last call from what I've read. I'm sure there are some other cities or states with late last call requirements but I'm only familiar with these ones. Occasionally in my city, there are special exceptions like New Year's Eve where bars can stay open and serve all night if they feel like it.
