fatfrog thanks for the reply. I'm actually hoping to dip in and pick up some small pastries, food, and other sundries to bring back with me - think security will give me any issues?

I've done a pickup like this before with other cities. I'm not filling my carry-on with food, just want to get a few things. I'm there - might as well. But if it sounds like its going to be a hassle, I'm probably going to forget it.

Not hoping to sit for a nice lunch or anything - really just pick up and go.

edit: Sorry, should have also mentioned, I'm debating between public transit and a taxi. I know that renting a car, even for such a short time, would waste too much time. I'm looking for opinions on taxi vs public transit in this time frame.
