Hello potential guests, visitors and members!

Irvine Underground meetings are held at 7pm on the second Friday of the month, every month.

We meet at Blue Hummingbird Coffee and Kitchen off of Jamboree and Main.
1 Park Plaza STE 165
Irvine, CA 92614

We occasionally host additional gatherings or events which may be posted to this site.
Please mark your calendars and this page for updates and we can all stay on the same page.

Since 2008, we met at the IHOP across the street from Gulliver’s. Back then, IHOP was open 24/7/365, and let us meet in their upstairs dining area. Starting March 2020, IVU shifted to virtual meetings.

In 2022, we returned to physical meetups, but learned that IHOP closed their second floor meeting space (and started closing at 8pm). If you remember eating pancakes with your hacker family, we’re still here!

In June of 2026, Gulliver’s permanently closed. The building will be demolished for development projects.  We have since moved to a newer locally owned and operated business down the road; Blue Hummingbird Coffee and Kitchen!

If you see any odd-looking technical folks who call themselves IVU while enjoying a steak sandwich, you’re in the right place
