I've been to DW for the past three years, and must tell you that the food is terrible, and the place is a massive ripoff.
Grilled chicken wrap - very little chicken, some shredded lettuce, and a mouthful of wrap bread.
Falafel - three balls with about a tablespoon of salad.
A hot dog is a safe bet, but costly, and the chicken nuggets are standard Kosher Delight frozen fare.
So you're better off bringing food from home and eating it in your motel.
