Halloween haunts and events are popping off around Southern California, but which ones serve the best cocktails?

A typical offering at most Halloween celebrations includes a delicious drink, sometimes with a festive name like the Banana Ban-Chi or The Beetle’s Juice. Whether you’re looking for a punny drink or prefer to sip your booze from an IV bag, we’ve compiled a list of five bars and speakeasies across Southern California where you can get a taste of the most hauntingly delicious drinks this season.

Don’t fret if you can’t make it to some of these bars before October ends. We added a few with an extended last call and others year-round for Halloween lovers.

Here are five cocktail bars and speakeasies to visit. For the most up-to-date information, check the websites of each location, as some require reservations or tickets for admission.Frankenstein’s Mad Scientist Cocktail Bar

Los Angeles’ latest Halloween pop-up bar invites guests into Victor Frankenstein’s laboratory. Is it a bar, or is it a science lab? Either way, it’s covered in cobwebs. Bartenders serve the cocktails in beakers and on metal trays. Visitors can watch as the mad mixologists cook up various concoctions. Ever tried a martini that changes colors and smokes? Admission includes a 90-minute reservation with one cocktail and lets guests take photos with the Creature and other spooky props like the light-up jack-o’-lanterns. And if you dare to look into your future, try your hand at a tarot card reading.

Secretary Club

This speakeasy is found inside Killer Queens Social House in Riverside, and this Halloween, it’s bringing the spookiness with cocktails like the Blood Rag, Black Dahlia and Frankenstein.

Guests can also have a drink served in an IV bag. This speakeasy is a fun, low-key hangout spot where guests can enjoy small bites like the lobster flatbread, barbecue beef sliders and a shrimp cocktail.
