My favorite CS in DL is Redd Rocket's Pizza Port. DD8 and I usually share the Chicken Fusilli.

They also have some very good (large) salads. I really like the Chinese Chicken Salad. And of course, they sell pizza by the slice, or whole. Pizza Ooh Mow Mow at DCA has the same pasta but, to me, it's not as good. Also, the salads at POMM are definitely not as good-they're served in a plastic box, with dressings in foil envelopes. The salads at RRPP are tossed with the dressing (you can get it dry) and served fresh all day.

Same price.
Also, we've recently had the chicken strips at Stage Door Cafe in FL and they are pretty good. Some of our group wanted to eat at Rancho del Zocalo and I went to SDC to get DD8 something. I was going to order her the kid's meal version for $6 but decided to order the adult one for $8 instead and I would share it with her. (She already had a drink) The adult version has 3-4 (I think it was 4) fairly large chicken pieces with fries. It was more than enough for DD and I to share. I think the kid's one only has 1-2 pieces. So, if you get the adult version, 2 kids or an adult and kid can definitely share them. DD and I have done this several times.
We finally tried Bengal BBQ last summer and didn't care for it. It was pretty tasty but the portions were really small. DD got a Cinammon Snake (pastry thing) that was pretty good but it's off the menu now.
I don't really have a favorite CS at DCA.

They are lacking in my opinion. Last week, for the first time, DD and I grabbed a burger at McD's Burger Invasion. We each got a hamburger Happy Meal for $5 each. I was going to get myself a double cheeseburger (hold the cheese) for $6 and order it without the fries. (I could share DD's fries). The CM said it's only $1 less w/o the fries, so I decided on a KM burger instead. It's only $5 and inc. fries and a small drink. It was really hot that day so we weren't really very hungry. The burgers were good, standard McD's fare. We took our food next door and ate in inside at POMM. (ahhh....the air conditioning

)
We've really never had a meal at Taste Pilot's Grill (only snack) or Award Weiners, though I've heard good things about both. We've had snack at Bur-r-r-bank Ice Cream and Bakersfield Bakery. Both are very good. Lately we've been hooked on the cinammon twists at the Bakery.
ADDED-Sorry I just re-read your original question and see you were asking about breakfast. So, my choice would be something from Bakersfield Bakery. Only problem is they open when DCA does and that may not be early enough for breakfast.
