Thanks for nothing, Charlie, now I am hungry
...
...
...
...for Mexican food!
I took a look through Brian's link above, and they are prevalent throughout my home state of Queensland.
In Brisbane, they appear to be (g)astronimically popular, the go-to restaurant for that cuisine.
In my day in that city, it used to be spots like Montezuma's and Taco Den and so on.
I have been living rural for over 23 years now, and my nearest one is one of two in Toowoomba, 143 km from me. I have not done a Toowoomba trip in over 4 years, so won't be there anytime soon to comment.
I may do a Brisbane trip (200 km each way), in the next few months, if so, I will try to remember.
Regrets I cannot be of further help.
