I actually also haven't found the cs food at DHS awful. It doesn't have a huge variety like Epcot and we have in the past generally gone with Sci Fi or Prime Time when we were at DHS. However, in June, we tried ABC Commissary for the first time in a long while and we loved it. My kids were starved, it was hot and we went in for an early lunch. Dh and I split a Cuban sandwich and this Asian salad. The kid got fish and chips. It was all very good, in fact the sandwich was outstanding. It came with plantain chips which were also very good and a bit unique (they will gladly sub fries for the plantain chips). I found their menu to have a nice mix of standby's (burgers, fish and chips) and something different (the Asian salad, a curry bowl and the Cuban sandwich). In fact, we returned a couple of more times before the end of our two week trip. That sandwich in particular was delicious. A recent thread about this place had lots of people talking about how much they liked it. I also enjoyed the atmosphere, it was nice and cool and I got to have a booth to sit in which was really nice!
We also love Sci Fi and Prime Time, in fact, in twelve trips to WDW, we have eaten at Sci Fi every single time. We just love the atmosphere and the burgers.
