Orange county must eat
Spending a week ( aug 15-22) in laguna hills looking for outstanding hole in the wall Mexican or BBQ
Price isn't issue
Food is main goal
Where do you go?
Coyote Grill is a hole- in-the-wall Mexican that does terrific Mexican style breakfasts on deck with a bit of a view. It's in south Laguna on PCH.
I will second Coyote for fun Mexican, but it is hardly traditional. My favorite hole in the wall for fish tacos is Los Cotijas in Tustin. You want to go further north up the 5 into Santa Ana for other real Mexican options.
If you want Cal-Mex, Taco Rosa in Irvine is good.
As far as real BBQ, again I will point you north to Santa Ana and Burrell's BBQ.
