I guess I had a very different experience at Murphy's than the other reviewers. I was underwhelmed with the portion size of my club sandwich ($9.69 after-tax for the sandwich and a few blueberries/strawberries). It was a good and satisfying sandwich, don't get me wrong, but there certainly were not any leftovers, and I have never even thought about going back.
Do ask for extra mayo on the side, because I had so little that the sandwich was indeed dry, and the flavor of the mayo was hidden. Murphy's is actually a converted house, and there are very few items from which to choose. I suggest calling ahead because it took 10 minutes to place and get a cold sandwich order when I was the only customer in the place. I also suggest asking about their box lunch specials that are priced less than the regular menu. I believe they feature one sandwich (ie, no choice) in the box lunch per day. They also cater.
