I have a friend who doesn't get sick very often...but she's eaten at Quizmo's twice and gotten sick twice. No such problem for her at Subway. Sure, you can always always find a better sandwich somewhere, but the price/quality/value dynamic at Subway is pretty darn good. Beats a lot of other "grab and go" choices. My only complaint is a little too much bread versus filling.
And Roger.... I understand where you're coming from. I actually feel you can get as good a meal in Ireland (or the UK) as anywhere, (despite assertations to the contrary). However, I think the U.S. and Canada do a much better job than Europe when it comes to the quality, variety, availability, and price of fast food options.
I'm not sure this is something we should boast about, however!
