I've only eaten there once or twice, I think they expanded to my area too late. One chain that stands out for huge portions was called Claimjumper. Looks like it's still around.
Claim Jumper is barely around, they have closed many locations in the past decade and Landry's sold the entire chain to a group of franchisees, if I remember correctly.
CJ was quite good back in the day but I have not been to one in years -- in my opinion, quality declined a bunch and doesn't match up with their prices. Cheesecake Factory, on the other hand, has maintained high quality, tasty food in generous portions (in my opinion).
