Located outside Neiman Marcus on the lower level of Plaza Frontenac mall, this bistro-style restaurant is designed in taupe and ivory tones with hardwood floors and glass Moravian accent lighting. The menu changes daily and emphasizes seasonal and vegetarian specialties, many of which are cooked in a wood-burning oven. Try the Portobello mushroom stuffed with spinach, ricotta and Bel Paese cheese, roasted and served with an arugula-fennel salad. Reservations are recommended.

This contemporary-styled Italian-Mediterranean restaurant features portabella mushrooms throughout the menu. Start with grilled portabella and asparagus topped with a balsamic vinaigrette. Entrees include specialty pizzas, house-made pastas such as goat cheese with smoked ravioli, and fresh fish and seafood dishes such as porcini mushroom-encrusted sea bass. Reservations are recommended.

LADUE. The rustic, yet sophisticated decor of this comfortable eatery with its warm woodwork and paned glass is a cross between a barn and a countryside manor. The classic Southern European menu features French, Spanish and Italian cuisine, with superbly prepared bouillabaisse, black Angus fillet on a round of grilled polenta, and casserole marinière made with shellfish and vegetables in a fragrant broth. Reservations are accepted.
