What a craphole. Ugh. Dirty, dank, and ugly this is not the place you want to spend a layover. Absolutely atrocious food options and very few power outlets just add to your misery. Finally, you have the lovely sight of gambling addicts getting their last fix pouring money into slot machines that are all over the place.
On the bright side, the Mexican place in concourse C does offer you a shot to go with your beer. You may want to take them up on their offer if you're going to be here more than an hour or so.
