We enjoy the Cantina Laredo in Scottsdale.....it is corporately owned.
They offer some intersting selections and a great tableside guacamole.
Try their mole's... also well done.
If you sign up online for their eclub...you get a free tableside guacamole!!!
I've been there, twice.
The first visit was not so good. I popped in for lunch. This was probably two years ago. Service was good and very friendly. I ordered cheese and onion enchiladas. I wondered where the onion was, and thought they might have used Hormel chili. I notice that the current menu just says "cheese enchilada".
On my second visit, a few months ago, I avoided the type of food that I could get at a thousand independently owned Mexican places in the Phoenix area, and ordered some seafood. I think it was halibut. This was much better, just expensive.
