Opening in the space left behind by the lackluster Pacific Rim Restaurant, Asiana is an extremely welcome addition to the I-83 corridor dining options, which, unless you really, really like chain restaurants, are limited. Asiana has a daily lunch buffet and itís OK ($7.95 Monday-Friday, $9.95 Saturday and Sunday). The kitchen really shines, however, on ŗ la carte items. They have a real touch with lamb, which is offered in nine different preparations (each $14.95). So far the favorite is lamb bhuna, hefty but tender chunks of lamb slow-cooked with tomatoes and onion; the spices do a slow burn, blossoming suddenly and fiercely. A deluxe malai kofta ($10.95) headlines, with rich paneer (cheese) balls in a delicately spiced tomato cream sauce. Other vegetables also receive star treatment: the cumin-scented bhindi masala (fresh okra dry-fried with tomatoes and onions, $10.95) is sensational, as is the unexpectedly light aloo methi (potatoes cooked with fresh fenugreek leaves, $10.95). Asiana so impressed us that we ventured to try its samosas ($3.95 for two), the leaden-textured bitch of bad Indian restaurants everywhere. Amazingly light and flaky, Asianaís samosas are flat-out the best we have ever had.
