B-SIDE: Café à la C'art, 150 N. Main Ave. Sweet dreams are made of this: cream, fresh fruit, perfect glazes and chocolate, lots of chocolate. Tucked away behind the Tucson Museum of Art, Café à la C'art purveys fine lunches and even finer desserts. The cakes are luscious, rich and thick. The tarts are small and tantalizing. The cookies are huge. A charming patio provides a quiet spot in downtown to watch the birds, listen to the waterfall and slip into a chocolate-induced purple haze. Café à la C'art is only open days, but you can take away a piece, a whole dessert or arrange catering for the post-concert party.
