And as near as I can tell, I've pretty much exhausted the options for sit-down breakfast. With two categories to consider, here is my judgement.
The first is the 401 Diner, named for its address on Fayette St. This place has the look of an old school diner from the outside, and inside follows suit, with a jukebox that skips incessantly and waitresses whose voices are baritone or bass from decades of smoking. Food is reasonable in price, size and quality, but this so-called "diner" has one fundamental flaw. They are not open 24 hours a day. In my book, that's pretty much the definition of a diner, so this place loses some points for that reason alone.
The only other place in town for a sit-down meal is Boccella's, a small, quaint operation at 521 Fayette St. This place first caught my eye after the day of the Pennsylvania democratic primary, when Hillary Clinton came to town and got a chicken cheesesteak here. Myself being an ardent Barack Obama supporter, it made me avoid this place for a time.
But soon I caved, going here one morning with Bernadette and our co-worker Shar. They had a very good breakfast menu, inside a comfortable atmosphere (though somewhat small) with young servers. This is usually a warning sign for me of trouble to come, as none of them looked older than 16. But these kids were on.
While the 401 Diner wins with regard to hours (open for dinner every night with breakfast all day), they lost those points for not being a 24-7 operation. And Boccella's, while nowhere near to a 24-7 place (closing as early as 3 pm some days), beats the crap out of that stupid diner. Their food is superior by leaps and bounds, their service is friendly and expedient, and their prices are just as reasonable.
Thus, the best dine-in breakfast in town is at Boccella's.
