I have been eating Panchos since the 80's. If you have ever been there you know how good it is. It is by FAR the best burrito shop in the east bay, and I have eaten at all of them. Try the BCR's.

We recently relocated to the area, and stumbled upon Los Panchos, and it is so good. The food is consistently great. Yes, they are always packed, but that says a lot about their food! Large portions too. It is definitely worth trying!

The Best in the Area (A LARGE AREA)!
I found out about Los Panchos at a party; they provided the catering. I was so impressed, I made it a point to find out about the restaurant. I have since eaten there a few times and used them to cater a party of my own. I have never been disappointed with their service or food and I recommend them to everyone. They have a good thing going on over there.
Recommended: You must try their carnitas items (burritos especially).

Los Panchos - Pacheco
I almost want to give Los Panchos a terrible rating, just so it won't be so jam-packed every time I go. But, alas, honesty wins out. This is the best Mexican food I've ever had! (And I've had a lot to compare) Let's see, I've had their tacos, burritos, chile relleno, enchiladas, salsa/chips - all delicious. You really can't go wrong. The only problem is it's all take out, so I have to order more food. Something to eat in the car on the way home (otherwise the aroma in the car would be unbearable) and I have to take some home for the family - there's no way I could have Los Panchos and not bring enough home for everyone! Two thumbs up - A+
