Jersey Mike's is decent airport food. Gayle and I were connecting through LAS and this place was close to our Southwest Departure gate. I ate my sandwich (forgot the number but is was turkey and cheese) at the Pei Wei Bar and had another one made for my 20 year-old son to eat at the gate. A nice sandwich and beer is always a good combination.
Note to the Wise: Bringing a sandwich on your flight is a good idea, but for the benefit of your fellow passengers, try not to make it tuna fish.
