This place happens to be attached to our office building. I considering trying it out once, but after viewing the menu, I changed my mind. When a Groupon became available, I thought it seemed worth a shot.
I waited around for over 30 minutes for one roast beef sandwich and a pickle. The Groupon was supposedly for $10 worth of food, but given the size of the sandwich, it doesn't seem like it would be worth it.
When I got back up to the office, I noticed that they had put mustard on my sandwich, when I had asked for none. I grudgingly plodded back downstairs and had a new sandwich made very quickly. The store was quite busy, and only one person in the kitchen, so I can understand their difficulties.
The staff were very apologetic, but there's enough other options in the area that I don't think I'll be back.
