This casually elegant BYOB serves up delicious gourmet American enhanced by global influences.

Great dining experiences are rare. Some restaurants, of course, serve excellent food. Others are staffed by servers who know exactly how to guide a table of diners through a meal. But rarely does everything come together as seamlessly and unpretentiously as it does at Alba, a sophisticated eatery offering delicious American cuisine with a touch of the exotic. Since Alba uses locally-grown ingredients, their menu changes twice each season to ensure that everything is served at its peak.

Our meal began with complimentary amuses bouches of a root vegetable and apple purée drizzled with extra virgin olive oil. These arrived in demitasses and were portioned perfectly-they woke up our tastebuds without filling our stomachs. The base note of root veggies was enlivened by the acid of the apples, and the oil tied it all together perfectly. It had been a long time since I'd had such an auspicious beginning to a meal.

The Torchon of Foie Gras ($12) was wonderful. Foie is usually served with a sweet, cloying sauce, and because of this the beautiful earthiness of it is unnecessarily hidden. But Chef Sean Weinberg served his with a simple, almost Zen-like accompaniment of poached quince, pomegranate gastrique with a smattering of whole seeds, and a wood-grilled crouton. As with all of the food I tasted, this appetizer was plated with only those ingredients that were absolutely necessary. In this restraint, Alba's food achieves an intense and unlikely elegance.

The Bosc Pear Salad ($9), too, was extraordinary. The pear itself was roasted with honey and rosemary, and it was so deeply flavored that I would have been happy had it been served alone on a plate. But in this salad, it was accompanied by a silky, Hormonyville blue cheese, bracingly bitter baby greens, and a maple vinaigrette that somehow brought all these disparate ingredients together.

As the waitress cleared our appetizers, I actually became a bit sad. I was, after all, fairly certain that the best part of the meal had passed. How could the entrées ever live up to the fireworks of the dishes we had already enjoyed so much?

I need not have worried. The Roasted Halibut ($24) was moist and generously portioned, and perfect for this transitional time of year. The side of velvety corn custard tasted like the best of the summer's crop, and reminded me of the warm days that had just passed. But the smoky bacon and champagne vinaigrette was pure cool-weather food, with rich flavors and hearty aromas. In this way, the preparation of the halibut, and its accompaniments, mirrored the transitional nature of the season.

The kitchen was just as adept at preparing meat. The Pork Loin ($23) was filled with an apple-and-fig stuffing and roasted to a gorgeous pink. The sliced medallions arrived resting on a pile of astoundingly light sweet potato pudding and next to a turnip-apple hash. Unfortunately, the apple-and-fig stuffing was completely overshadowed by everything else, but the dish as a whole most certainly made up for the shortcomings of but one of the parts.

The Main Line is surely becoming a world-class restaurant town, and Alba's addition to the scene will only help solidify the area's place on the culinary map.
