Wow, I never even knew about this event. Is it like a swap meet, or more of a hang-out session? I also freaking love Portillo's! I just went there for the first time when I was in Chicago a couple months ago, and was hooked instantly. I found out there's one in Moreno Valley and the one in Buena Park, so a trip to either is in my near future. Unfortunately I'm not available to attend this event tonight, but it looks like a cool gathering.
