Sacramento's Best Kept Secret!.
If you want great Mexican Food, and you only care about the food, I don't think you will find better food for your dollar than Adalberto's.
First things first, their food is excellent! I have lived in Mexico, traveling in many parts of it for a few years, and the food is very authentic. Enchiladas, burritos, tortas (sandwiches), tacos, you name it, they have it and it's all good. Their combo plates are less than $7 and their portions are huge.
I have eaten at many Mexican restaurants in the Sacramento area, and I have yet to find one that has food as good as Adalbertos. That having said, they have locations all over Sacramento and a 24 hour drive-through. Give it a try, you won't be disappointed.
