Sorry, just realized I missed answering part of your question....
In general it's good...but the menu is limited. There's a cold line and a hot line. For lunch/dinner, the hot line does burgers and chicken nuggets and fries, while the cold line offers deli sandwiches and salads. While your choices are limited, the food is fresh and the portions are huge. They have a lot of baked goods, including a fabulous cookie called a Magic Bar, and good muffins for if you want to grab something small and quick for breakfast.
I don't recall how late they stayed open, so I can't answer about a late night snack.
The only problem as I mentioned in my other post is the size...both the area where you order and the dining area are small, and get crowded easily during peak times. If you can send only one person in to get the food, then do so, especially if you have small kids/and or strollers.
