I'm so glad someone opened this thread again. I worked in Waukegan for all of 2015 before I started working at the Tribune, and tried a fair number of options in the area. I found a few solid places, which made the horrendous commute sort of worth it. None are quite worth making a trek all the way from Chicago for, but are a great side trip if you're in the area.
I wish I had more pictures. But since I don't work up there anymore, I don't have the option.
BTW: There were a number of Filipino places up in Waukegan and North Chicago.
Sazon
Enchiladas with Tomatillo Salsa The best place I tried by far was Sazon. It's a charming little storefront in the middle of Waukegan, with cutesy signs on the wall. Great enchiladas with tomatillo sauce, which tastes like they actually made in house. Very good pollo con mole rojo and chile relleno. I was so excited when this place first opened, and went nearly every week.
I'd wholeheartedly recommend this place if my last couple visits weren't a little off. There seemed to be a new cook in the kitchen, and everything felt a little sloppy, where it had been clean and clear. Hopefully, it's back on track. When Sazon is good, it's very, very good.
Hours are a bit difficult. It's only open Thursday through Sunday.

http://www.sazonwaukegan.com/Birrieria JaliscosThis was close to the office, so we went here a lot. Freshly made birra with handmade tortillas. Not in the same league as Zaragoza or anything, but immensely satisfying on a cold winter days. Ordered the goat tacos often, and the tortillas were always warm and soft. Interesting array of salsas on the table.

El Rey del Pollo AsadoFrom the moment you step out of the car in the parking lot, you can tell this place is about the grill. The smoky grilled chicken is quite good, if occasionally a tad dry. Great salsa bar and the sides make for a satisfying lunch.
