Oneiron, there's a place I used to eat at a lot for breakfast (they had this huge breakfast sandwich with sausage, bacon, eggs & cheese) called Coppell Deli
. It's in the heart of Coppell, between Lewisville and DFW. Looking on the map, the main road is Bethel, and that's what it would be on, right in "downtown" Coppell (really just a wide place in the road).
It was a rustic
little place that was usually busy. John Madden used to recommend this place when he did Dallas games. A few of the Cowboys were supposedly regulars here.
That area has exploded with development the last few years, and it's been a couple of years since I went to Coppell, so I can only recommend this place with the "disclaimer" that it may have changed.
If you happen to go there, I'd love to hear your "review" on what it's like now.
