For the size of this airport, it really lacks places to eat. I think the slot machines take up valuable vendor space. There are even slots in glass enclosed spaces which is the smoking section.
Terminal 1 and 3 are connected by concourse D that you can get to by tram, after security. Don't be fooled by the taxi driver that wants to make a few extra bucks because he will try to convince you otherwise and drop you off at the furthest point possible.
I've arrived several times where the taxi line was a good 30 minutes long. Luckily, during my recent trip, there was no line. Same with TSA, no line at all, which was surprising.
There was a really cool hologram named Jennifer giving directions to the tram. It was freaky that her eyes followed your movement.
