It may be Margarita Monday and that jumbo souvenir size is two-for-one, but at approximately 800 calories, it's not a good deal for your waistline. If you're craving a margarita, stick to the smallest size and order it on the rocks. Save a few hundred calories by staying away from any cocktail that could be a dessert (anything with chocolate, cream, multiple liquors or fruit juice). Stick to the classics, like a dirty martini or a vodka soda. If you're making drinks at home, try the low-cal Baja Bob's drink mixes.
