I was there at the end of August and the choices were a hot dog, bahn mi pork sandwich, spicy chicken sandwich, chicken fingers with a sauce, or chicken Caesar salad. They all come with a side (apples or homemade chips) and a bottled drink. They have your lunch sitting out at Tomorrow Terrace with a name tag.
We picked the spicy chicken sandwich and it was ok. You will be hungry and anything would have tasted good at that point!
