Where: 201 West Carrillo Street, 962-5999, quantumrestaurant.com.
What: Comfortable yet classy seasonally inspired American grill.
How much: Appetizers from $5-$16; burgers around $14; entrees from $15-$35.75.
The dish: It’s rare a place tries to be many things to many people and pulls it off, but Quantum does. It’s a lounge, with hip music, a cool setting, and great cocktails. It’s a place to nosh, with terrific fries and other fried things (calamari and rock shrimp, say). It’s a place to get one of S.B.’s best burgers, and you can build your own. For those of you who want a bigger, fuller, fancier meal, kick it off with foie gras, enjoy that duck two ways with a seared breast and leg confit, and close with a spiked milkshake. The wine list not only offers many faves from over the Santa Ynez Mountains but surprises, too, like Jim Clendenen’s racy gew¼rztraminer, One Spicy Meatball. Add in some of the best service in town-just the right blend of friendly, attentive, helpful, and absent so you have your good time-and you’ve got a restaurant that’s perfectly pleasing.
