I could be wrong, but I think the menu at Della is more limited on the weekend. I'd definitely give it a try if you're not in a hurry to get anywhere. You may even be able to order it to go and just sit in that little courtyard near it if it's a nice day out and the wait is long.
Jackson's looks good! That Cubano Stuffed Flatbread is calling me, but *ouch* at $16!! Do report back on what you had and how you liked the place.
