The rusty one sounds like a joy! I hate that though when you find a good thing in a place you haven't tried but the rest of the offerings are not really up to standard. Although the steak one probably looked the best photo wise then ended up being meh.
Anyway, deeply envious of your many taco joints, we have precisely zero in Scotland!
I'm perfectly fine with getting a tray full of Rustys the next time. Maybe a margarita too. You know the restaurant business is suicide, but you could totally make a taco joint if you wanted. You know how to cook, make sauces, etc and you have a proper appreciation for peppers.
Cheers man! I have thought of it before actually. It would be cool because over here there is so much less variety yet people are screaming out for different things. Of course I am a pure coward and like the easy life so might let that stay a pipe dream :0)
