Since the Famous 4th Street Deli has changed hands, and since we'd had Manny's (Chicago), Corky & Lenny's (Cleveland) and Katz's (New York) within the last 10 days before this trip to Philly, I was ready to venture to a non-deli breakfast choice for our morning after.
I found two options that sounded appealing -- Morning Glory Diner on 10th & Fitzpatrick and Sabrina's at 910 Christian. Sabrina's is near the Italian Market, and is rumored to have interesting pancake creations (like pumpkin/pear pancakes and corn cakes)
The Morning Glory is near by -- a few blocks closer to South St (which is actually a bit to the north). Morning Glory specializes in frittatas. I also found a mention that the owner makes almost everything from scratch that she serves including her catsup. I gave Griffin the choice between these two and he picked Morning Glory.
We arrived around 10ish on a Tuesday morning. The place was somewhat busy given that this was probably a "between" meal time (6 or so other parties, mostly singles). I'm pretty sure everyone else was locals.
We ordered a wild greens, smoked ham and potato fritatta with grits on the side, and a special of the day which was a brie, granny smith and proscuitto frittata with carmelized onions. The frittatas were cooked perfectly. Light, puffy, and still moist in the center.
The potatoes (home fries) were seasoned with thyme. A bit too much thyme for my tastes, but still done well on the grill. Grits were wonderful, light and grainy. They went especially well with the wild greens and ham. The biscuit was the dryish, crumbly sort. Very good with the homeade blackberry jam on the table. But who had room? The frittatas were huge.
Unfortunately we didn't have anything that needed the homemade catsup -- the potatoes already had too much thyme on them. We ate it anyway of course. A very interesting flavor -- not the usual sugary vinegery condiment. It had a distinct curried flavor -- like an indian curry with cloves and ginger and was a little fruity too.

Coffee was quite good (strong for a diner) and served in interesting dineresque stainless steel mugs -- not that we had ever seen such a thing at any diner before. A couple regulars ordered the veggie burrito. Clearly a great place for vegheads. All in all, the food was quite good. Plus, I really respected what this owner was trying to do.
If I had prepared by reading HollyEats.com before this trip, I would have known that his top two choices (or atleast the 2 I found with 5 greasestains) in Philly for breakfast are the Down Home Diner in Reading Terminal Market, and Carman's Country Kitchen at 11th & Wharton.
He favorably reviews Sabrina's (4 grease stains), but either hasn't made it to Morning Glory yet, or has, but doesn't post unfavorable reviews (I am pretty sure he used to have a review up for Famous 4th St Deli from before it changed hands, now it is only for Famous 4th St Cookies, which are still produced and owned by the original owner). No mention of the deli any more...
I am rambling now but I guess my point is that LTHer's might appreciate the memory jog/info that Philly is HollyEats' home turf. I knew this once, but forgot. In rediscovery of that fact I happened upon mention that Cathy2 has met (what I assumed to be a her), and then further discovered, that Cathy2 has met *him*. Either way, HollyEats.com is a great site in the same spirit as much of LTH.
And, the Morning Glory was a nice neighborhood spot for breakfast.
