A tireless attention to detail and a relentless focus on quality make this restaurant a standout.

Chef Alison Barshak travels to the Deep South for her grits. If that doesn’t say everything we need to know about her cooking philosophy, then nothing does. After all, it’s not as if they’re truffles from Piedmont or fresh lavender from Provence. It’s not as if grits enjoy a reputation as a great luxury ingredient. At the end of the day, they are as humble and simple an addition to a dish as one is likely to find.

But there she goes, year after year, to the World Grits Festival in St. George, South Carolina, to choose and lug back how ever many hundreds of pounds of the stuff she needs. And while the uninitiated may wonder why she would go to such lengths for such a seemingly basic ingredient—I know I was perplexed before tasting the fruits of her travels—all it takes is a single bite of what she transforms them into for it all to make sense.

The grits weren’t the focal point of my softshell crab appetizer ($15), but they added an undeniable (and charmingly paradoxical) note of rustic luxury to the dish, as well as an extraordinary textural counterpoint. The sautéed crabs themselves were brightened by the addition of a lemon-herb butter and given depth with an artichoke aioli. But they were most notably set off by the truffled hominy croutons, delicious little buoys of unexpected richness that anchored the entire dish.

And it goes beyond grits. There is a certain Alice Waters-like concern for freshness and authenticity in Chef Barshak’s cooking that, while certainly more common in the region than before, is still rather rare in these parts.

Her Parmesan fried oysters ($12.50), a riff on the classic Rockefeller preparation, maintained a bracing, briny flavor inside the crust, creating a fascinating taste and texture tension on the palate. Bacon, horseradish, crisp shallots and creamed spinach also made appearances, though because these components were deconstructed (in other words, they weren’t all piled atop the oysters themselves, as they traditionally are), their individual characters had a chance to shine in a way they normally don’t.

Entrees, which like the appetizers are constantly changing, might include impossibly fresh pepper-crusted tuna with shoestring potatoes and a sherry-shallot broth ($25) one night and insanely tender magret duck breast given added interest with the exoticism of star anise and the familiar tang of rhubarb ($25) on another. Or they may available. I’ve been to Alison at Blue Bell twice now, and both meals were extraordinary. What always strikes me is the haute cuisine quality Chef Barshak brings to all her dishes: Cooking temperatures, seasoning, the careful manipulation of heat (her chili-dusted skate is fabulous). It’s like that news station on the local radio – All tasty, all the time.

Even desserts ($7 each) tend to leave me speechless—and I don’t have much of a sweet tooth. The walnut sticky bun ice cream sandwich has as much depth of flavor as most restaurants’ entrées, and the white chocolate bread pudding, even discounting its sinful banana bourbon caramel sauce, was far more flavorful than the majority of the other versions of the dessert in the area. At least, that was my impression of it: I happened to look away from the table just as the waitress brought it over, and by the time I refocused my attention on the task at hand, Ms. M. had finished most of it. Her glazed-over eyes and barely audible signs, however, spoke volumes.

Alison at Blue Bell is relatively small—it only seats 65 inside and 20 on the outside patio—but the menu covers as much ground as restaurants twice its size. And because of the warmth of the space and the chef’s regular rounds through the dining room, introducing herself to guests, chatting a bit at each table over the course of the evening, Alison at Blue Bell has maintained a charm and an informality that is unique to the region. What she started at Striped Bass all those years ago (she was its first executive chef) seems to have come to its logical conclusion at Alison, where all her talents are on display.
