Rib-eye steak is one of the best steaks you can ever grill and what makes it really great for grilling is the fat rings that make the steak appear pink as you can see in the photo below and the flavor that those fat rings create in the grilling process.
If you can't find a ribeye for grilling, you could also check for prime rib and cut it to portions or a cheap option could be the top sirloin which has a good amount of fat in it as well and flavorful,but what you do not want to get for grilling is any dark red meats like the chuck steak which gets really tough and the flavor isn't the best unless used as stew meat or roast.http://healthyeating.sfgate.com/health-benefits-rib-eye-steaks-4413.html
