not on a Friday.

some bars/clubs stay open until 5am on Saturday nights.

We have clubs that go later than 2...but

we don't have any clubs that can officially stay open after 2am (3am on Saturdays) or 4am (5am on Saturdays) w/o regard for alcohol sales. closing time is closing time, period.

there are a few unofficial/underground/speakeasy type after-hours spaces that stay open after 4/5am.
