Somehow, the choice of M&S, nothing wrong, simply just another meal, for dinner in Austin strikes me as like unto breakfasting at Bob Evans/Denny's/IHOP when I could go to Cisco's, or drinking beer in a lobby bar, when I could sit out under the trees at Scholz's with a pitcher of Shiner and wait for the ghosts from my misspent youth to show up. Eat there? No, that's a misdaventure unless too befuddled enough not to be able to leave (a state which I have often attained.

A little searching and reading would provide all sorts of alternatives, several of them quintessentially "Austin", better qualified to mark a memrable visit, especially if you're not often in the city.
