They are very different experiences. Satuli is a good quality quick service place and Nomad is well... a lounge. Smaller, quieter, slower - a place to relax. But you can make a meal from the apps. We made it our dinner one evening (brunch at Tusker house earlier meant we weren't really up for a big meal). For four of us we ordered about 5 small plates and a few drinks.
We had lunch at satuli a different day and liked the food a lot. I recommend both but they are definitely different.
One more thought. The bill at Nomads after ordering enough food for a meal and a couple of drinks is similar to the cost of an average table service meal at Disney. At least twice as much as you would spend at satuli.
