Despite the expensive prices for basically everything on the menu there are still long lineups. This is because William's is the only place that serves food in the GH building. Humber's food emporium is just way too out of the way and far.
The food served here is pretty good. I would recommend their grilled chicken caesar wrap and their chicken pesto panini. I once ordered their caesar salad with a side of chicken and it cost me $11 =(. A salad should not be worth this much unless it was in a restaurant.
Long lines and expensive food deserve only a 3/5 in my opinion.
