I'm a lifelong, diehard Roberto's fan who frequented the first shop in Chula Vista, CA for decades. I moved to the East coast and look forward to driving straight from the airport to Roberto's before doing anything else on the way to my mom's. Well, it's over. I arrived Sun eve and went to Roberto's for my favorites and was hugely disappointed. The food had been losing its flavor for a while but this time it was actually bad. They don't make their own machaca (shredded beef dish) but now use canned beef - the kind that's bought at big box stores. It wasn't even chopped well or mixed with the vegetables. The beans in the mixed burrito were tasteless. The rolled tacos seemed stale and hard vs crispy and they put a lot less sour cream than they used to. My mom told me she'd take me to another place Taco y Taco and it was fabulous. I'm done with insisting on R's.
