Pie Face
After you've checked in your bags, don't rush to go through immigration. If you have some time head to the food court. Pie face has a myriad of pies, savory and sweet varieties will have you staring at the counter for a good few minutes. My personal fav is the chunk steak pie, with the stock which is a pile of mushy peas and mashed potatoes, topped with a smooth, light gravy to combine all that pie-y goodness. They come is a really cute pie face box to make sure your pie doesn't get messed up as you take it away. The prices are reasonable, but you may not find it filling enough on its own as a meal.
Still a great place to get your pie fix. They have just opened a store in NYC so I'm sure pie face is going to make its mark on the world... Not just at the airport!
