Denny's, the 24-hour American diner, opened a restaurant this week in Las Vegas with a wedding chapel where couples can tie the knot after a meal of bacon, peanut butter and bananas between two slices of French toast finished off with a bacon vodka chaser. The restaurant - with a photo booth in case couples forget a camera - is on historic downtown Fremont Street. Its modern curves, neon and steel are meant to fit in with the city's "over the top" feel, said Frances Miller, chief marketing officer. "A normal Denny's is not going to cut it in Vegas," she said.
