We actually felt like at least the soup and salad place and Sunshine Season wasn't a good value on the vouchers. They wouldn't let us get anything but chips as a side item. we were hoping to get a sandwich as our "main dish" and a cup of soup as the side (it's listed as a side on the menu) but the CM was insistent that it had to be nothing but chips and nothing but a cookie as the desert. Tith those options it would come to less than $11.50. It may be one of those deals where you get a different answer with a different CM though.
At the time I was looking to use them it was very early for lunch and the only counter open was the soup and sandwich place so I didn't look to see if there may have been better options at other counters.
