i only go to Red Robin once a year - when i get my yearly free birthday burger coupon. the reason is simple, there's no reason to. the bottomless fries are nice, but i've never been a big fan of their burgers, "gourmet" though they might be. they aren't terrible, for sure, but i can get better, cheaper burgers elsewhere.
the service we've had has always been good, so i have no complaints about that.
i don't get the redesign. gone is the family friendly sort of atmosphere they used to have. in it's place is a more slick and polished look and feel that will likely keep people from bringing their kids. i hope i'm wrong about that, but it felt like that's what they were aiming for. to be honest though, the new seats did look nice and comfortable, though we chose to eat outside.
