Glass Wall is a great new American bistro just where we needed it most: in the restaurant-deprived Heights. Predictably, the eatery has been packed since it opened in early April. Lance Fegen, former co-owner of Zula and chef at Trevsio, has left behind the overwrought designs and menus of his previous ventures and found his own cleaner, simpler style. Fegen is a surfer, and "glass wall" is surfer slang for a big wave -- it's also the name of a 1965 Jim Freeman surfing movie. The restaurant's interior design, which is built around a wall of glass and black stones, is light and airy. The open kitchen, visible from anywhere in the restaurant, invites spectators. The menu is heavy on seafood, although, oddly, hardly any of it comes from the Gulf of Mexico. With meats garnished with butter, vegetables accented with bacon, and boldly flavored sauces, the food manages to be sophisticated and hearty at the same time. The wine list, though short, is composed of a spectacular array of hard-to-find bottles. The menu changes monthly, to take advantage of seasonal ingredients.
