I’ve been going to Al Franc for several years. It never disappoints. While the carne asada is good, (you can get equally good on this side of the border at Tacos El Gordo), the adobada is the best I’ve had. About half the plates in the parking lot are US, so it’s a pretty mixed and family friendly crowd. Plus it’s location kitty corner from Costco makes it an easy destination once over the border.
