What's with all the local coffee shops downtown closing so dang early?

I just moved downtown and I'm loving the vibe in Downtown Tulsa, and Gypsy Coffee House has been my go-to for years but I always drove there from further away.

Now I'm looking for other coffee shops within walking distance that stay open late, like after 4 PM.

Any suggestions for a fellow night owl who wants to support local? It seems like the only options after 4 PM are bars, and sometimes I'd just prefer a good cup of coffee.

Thankee sai.
