We eat a vegetarian diet because we want to feel healthy. But that doesn't mean we don't want deeply flavored, interesting foods. Plaid delivers -- the kick-back, casual den strewn with sofas caters to a hip, multinational college student clientele. We like the salad "plaidders," omelets served all day, the "plaid" Thai noodles, Caribbean jerked tofu and lemongrass tofu served over rice. Some of the most exciting dishes show up as daily specials, like black bean pepper stir fry in Asian brown sauce, and Singapore curry. It's an interesting environment, too, earthy and hodgepodge, full of tree-hugging fellow diners, but with a full bar.
