Recently remodeled to replace the former Richie's Cafe here, Gus Jr's better marketing model should attract crowds from right off Interstate 215 and the entrance to nearby March Air Reserve Base. Known for their huge hamburgers, omelets and club sandwiches, the staff seemed glad to make changes and substitutions to nearly anything on the detailed, 6-column menu. The servings are well worth the money. I had a satisfying Baja grilled chicken salad with very delicious ranch dressing. Sorry, Coke fans, just Pepsi products here.
Due to closeness to I-215, access and departure is challenging as there is no direct entrance right into Gus Jr's from Cactus so westbound traffic, pay attention: Turn into the 76 gas station to maneuver your way onto the Gus property. On my first visit I had to take back streets and wind my way, eventually, into the Gus's back parking lot. The drive-thru is tight, but it works. All menu items can be ordered to go.
Bottom line: Gus Jr is certainly to be popular with March ARB personnel, freeway folks and patronage from nearby businesses. You should march right in and try it. I don't think you'll go away hungry.
