We've been to the new Shades every month this year except June (daughter was with us, and she'd rather cook). The food had greatly improved on our last visit. The grouper in the grouper sandwich was large and well-cooked just like the old Shades (as opposed to small and overcooked as in previous visits). I enjoyed the house salad with grilled fish and their signature sweet pepper vinaigrette.
If you're a fan of the old Shades, in my opinion you can only enjoy the new Shades if you just wipe those memories out of your head. The atmosphere is very cold, and it's very noisy. The waiters run around in a frenzy. Not like the funky, laid-back atmosphere of the old Shades.
We will be back, especially when we drive down for short stays in the off-season and don't want to take the time to grocery shop, cook, and do dishes. We also enjoy the sports bar atmosphere at Shades in the off-season because it allows us to dine while watching college football and college basketball which we're very into.
