There are actually several Green Eggs Café restaurants in Philadelphia. They call themselves a "brunch-style restaurant", so they are good for both breakfast and lunch (no dinner). Be prepared to wait for a table. Also be prepared that they are cash-only. The food is great--hearty, wholesome, filling. Before I found out I couldn't eat gluten, my favorites were always their variety of Eggs Benedict, especially the Short Rib Benedict (tender, braised short ribs served on cheddar hash browns and topped with poached eggs and horseradish hollandaise sauce). Or their imaginative pancakes and waffles. Now, I usually stick with the gluten-free "Eggs Your Way" with a side of succulent ham.
Old-school diner. OLD-SCHOOL. Like "I think I've been transported back in time to the 70's" old-school. Maybe the eggs and hash browns are a little buttery. Wait...that's a good thing! Maybe the coffee is not as good as Starbucks. But it’s good and it’s cheap and its down-to-earth. Sometimes your body just craves that kind of breakfast. It's worth it just for the experience.
Like the Green Eggs Café, Sabrina's Café has several locations in Philadelphia. They are always packed, but if you get there early, you will have a much better chance at getting a table. Although I cannot eat it because it contains gluten, their Stuffed Challah French Toast is (I'm told) amazing. It certainly looks amazing: french toast stuffed with sweetened cream cheese and topped with bananas and vanilla bean syrup. Did I mention that it is as big as your head?? Fortunately, they are very gluten friendly here, even making their wonderful Avocado Toast (with avocado, black pepper agave, roasted tomato, and the optional poached eggs) on gluten-free bread.
My favorite experience at their Art Museum location on Callowhill Street was going there with my Fiancée on a snowy Sunday morning at 8:30 AM. We easily got a table (most people dared not venture out) and had a leisurely breakfast with just enough time to have another cup of coffee at the nearby Starbucks before getting to the Barnes Foundation on the Benjamin Franklin Parkway at 10:00 AM. The Barnes opens to the general public at 11:00 AM on Sundays, but members (such as myself) are allowed in an hour earlier. The Barnes is one of the world's largest private collections of Impressionist and Post-Impressionist art with more Cézanne’s than the Louvre and more Renoir's than anywhere. It is, therefore, usually packed with humans. On this glorious day, however, between the snow keeping locals away and getting the member's one-hour head start on visiting non-locals, we practically had the museum to ourselves. When we arrived in the main gallery, for example, there were only four people there: myself, my Fiancée, and two security guards. In the other small galleries on both the first and second floors, for that first glorious hour, we were almost always the only two people there. Magical.
