I am shocked nobody has suggested the Golden Coral yet. Its near Fort Pierces walmart, and it is a drive away but its a glorious all you can eat, look at me i'm a fat beast, resteraunt. With any luck i'll be out at EFT in May to savour the treats of the golden coral. Also there is some mad chinese buffet as well hidden in fort pierce, however both were very cheap and i don't recall seeing many dogs or cats in Fort Pierce
