I'm not sure if Jelly Jams is open yet. Just a hunch.
Connies is a solid Greek Diner, but the last time I went, they had prewrapped food service breads for the bread basket offering. I think I was there last one year ago. I like their pancakes, and the turkey is real.
You might want to check on Robert Nava's (of Depot Diner fame) new venture which is a few blocks E of Connie's. Not sure what their deal is on Sundays, but they have a varied menu - steaks, seafood, pasta, sammiches, and a full bar. Search for Olive Or Twist in Berwyn.
We cannot be friends if you do not know the difference between Mayo and Miracle Whip.
