More than anything else, I loved the concept. With places like Subway, I always feel hurried into making my selections when there are people waiting in line behind me, but at Which Wich, you just pick out a bag, mark all the meats / veggies / sauces that you might want, put down your name and hand it to the servers. \nTheir buffalo chicken is really good, but that's the only thing I tried so I can't really say much about anything else in comparison. The veggies were really fresh and my sandwich was neatly wrapped up. I tend to be a messy eater, so I give extra points to anyone who wraps up sandwiches in a way that I don't get mayo down the front of my shirt. \nParking can get a little tricky since this is right in the middle of the Met area, and although I went here on a Saturday, I can imagine this place being really busy on weekdays during lunchtime.
