Don't believe I would pay full retail ($28 if I remember correctly) because we have morphed out of the "fill your plate till you burst" phase of our lives, but the 2fer makes it a pretty good play. Not sure if we've just timed it right, but I think we've eaten there three times (including a brunch a few weeks ago) and have never had to stand in a long line.
Quality of food is good - selection not overwhelming but varied enough to cover most tastes I would think. Pretty good array of shell fish which a lot of people like. Favorite was actually a soup they were serving that day - a kind of chowder featuring scallops and bacon - awesome!
We skipped the bubbly, so I can't comment on how often they fill the glasses (!!!), but from strictly a "grub" perspective, don't think you would be disappointed.
