Hi Mate,
If you're in a big city, the Halal food choices are plentiful and reliable. Most places here advertise "zabihah" halal, which is done according to the strict Islamic standards (meaning without the stunning or mechanical slaughter). There are Muslim slaughterhouses in the country as well. At Eid, some people actually go out to farms and perform the Qurbani themselves, my father amongst them. A very useful site to find out which restaurants or grocery stores serve Halal food is zabihah.com. Of course, there is never a 100% guarantee that a restaurant/grocery store is telling the truth about serving Halah. But any place caught lying has a lot to lose, so I don't think they would think the risk is worth it. If you don't mind me asking, why are you inquiring about this? You planning to visit the States anytime soon?
As for my actual name, I like to keep that private on the interwebz. However, drop me a line on dboy1425 at yahoo. com and I'd be happy to disclose it. :-)
