I would actually go with a 3.5 on this one... leading to a 4 star. My friend was way excited to see this chain pop up in the valley, so we added it to the pre-class dinner rotation and I have to say there are a few things I really like.
The staff has always been super nice. I'm a little confused about some of the negative ordering comments. Maybe if you called something in for pick up there could be an issue, but you are standing right there (subwayesque), so if it's not to your liking, say something.
From what I have been told, the menu is not "full" yet. They do offer a big version and a skinny version which we were told should be coming early 2013.
I personally like the wreck. It's a pretty perfect sandwich. And I love that they clearly post the calories. Having spent most of 2012 significantly reducing my body size, I want to know what I'm putting in it and that's not always easy to do when dining out.
The space is clean and open. The menu selection offers a little bit of everything. And I agree with Kate O, the dream bar is pretty much just that.
