We are just back last week, and I am sad to report that there is still not a good counter service in MGM. We had not tried the Flatbread Grill, so tried that this trip. Big mistake! This place is so AWFUL it makes the ABC Commissary seem good. Why they call it the Flatbread Grill is a real quandry--there is absolutely nothing on the menu that resembles or imitates flatbread of any sort!
Later in the week we ended up having a quick lunch at at Backlot Express, just because we didn't feel like walking any further, and it wasn't that bad, so if I had to pick one, Backlot would be it, but still not as good as most counter services in other parks.
