A good strain of Delawares may be what you are looking for. Delawares were the popular meat bird, and a Delaware x New Hampshire cross was the favored dinner bird until the Cornish X came onto the scene.
Let me emphasis that it is a _good_ strain of Delawares. We're talking about a flock that would be more expensive to start, but would quickly pay for itself in quality. The hatchery Delawares I have come across have been too narrow, flighty, and slender to really impress people. They can be used for the dinner table - and I'm sure that many people who have ordered them are happy. But they would be blown away if they had the real deal.
Dorkings are another really nice table bird, though they are even harder to get into than Delawares. White Rocks grow fast, too. I've been pleasantly surprised when I ordered White Rocks from hatcheries in the past. They are usually the first to feather out and will tower over the other breeds during the first few weeks. While I doubt they are as nice as proper heritage strains, it does look like the hatcheries have managed to maintain a really fast growing production bird. Some of the White Rocks I ordered were from Meyer Hatchery, and if you aren't looking at spending a small fortune then I'd recommend them.
Barred Rocks and New Hampshires also do well. Beyond that you're looking at nice birds that you select because they are pretty or because you prefer their other qualities.
