Our number one choice in DCA is WWS in GC.
Menu
Chicken nachos (almost everything on the side)
Hot Dog with fries (chili on the side)
DD11 and I shared the chicken sandwich and upgraded to onion rings at Taste Pilots Grill and it was pretty good. The onion rings were delish!
Menu
BBQ Chicken Sandwich-Taste Pilots has a condiment bar with all the fixins.
Haven't eaten at Award Wieners but I hear good things about it.
Finally tried Cocina Cucamonga Mexican Grill recently for the first time. My experience wasn't great. I had to return my
Fire Grilled Citrus Chicken - 1/2 Chicken seasoned in a savory marinade of cumin, garlic, cilantro, lemon and lime served with warm flour tortillas. $13.49 since the chicken wasn't served hot. I returned it to the window and they replaced it with another lukewarm chicken.

On the 3rd attempt they finally gave me a hot one. The CM at the window said the temp was around 175. I said, on the returned one, he said no, on the new one. What was the temp on the returned one? About 115! Too scary. Next time I want chicken I'll get the 1/2 fried at Plaza Inn.
Soon there will some new choices in DCA. I imagine the new Pizza Pasta place will be similar to Pizza Port (hopefully) If so there should be some good choices there.
I haven't been to Wine Country Trattoria since they reopened with new menu mostly because they got rid of my favorite thing there, the Pizzetta Salad. So now we make it at home.
Also, it literally only takes a few minutes to cross over from DCA to DL. So if you don't see something you like at DCA you can go into DL. Perhaps for the Fried chicken at Plaza Inn?
Ask for double mashed potatoes. The green beans are never any good.
