Denny's opened its first location in New York City on Friday and it's selling a $300 breakfast that includes a bottle of 2004 Dom Perignon Premier Cru Champagne. The breakfast, called the "Grand Cru Slam," also includes servings for two of eggs, pancakes, sausage and bacon. The price of the meal may be steep, but it's actually $100 cheaper than the the average rate for the same bottle of Dom Perignon at other restaurants in the city, the New York Daily News reports.
