The food is outstanding, the bacon wrapped dates have me starting to drool even now and the bruschette is nearly a meal in itself.
So, the food is great, but that's not even half of the reason you should stop in. During happy hour, they have 1/2 off bottles of Laurent-Perrier champagne. Check out the menu, you can get a bottle of their Cuvée Rosé for $76. This is the best sparkling rosé on the planet and Cento is one of the only places in Madison that even serves it. Not down for a full bottle? They also have 1/2 bottles of the brut and demi-sec for $21. This alone will keep me stopping in anytime I'm back in town.
