At first glance, Rubalcabas may seem a lot like a knockoff Roberto’s; in fact, the mascot himself looks like Roberto in an old-timey disguise while the space could certainly pass for one (or any other valley taco shop, for that matter). But rest assured, everything is just a tad more spot-on at Rubalcabas. And the steak and shrimp quesadilla — overflowing with cheese and elevated with the addition of enchilada sauce — is a destination dish. Plus, they’re open 24 hours, so go — now.
