I still fly a lot for work and unfortunately had a few hours to kill in Newark (shudder). Sawgrass reminds me of that airport. In the middle of all the gates there are restaurants and bars with people walking all around you. Its loud and noisy, sometimes you are bumped by those passing behind you, and it just has that "food court" vibe to it.
Others have mentioned the need for sound deadening, which is critical. I think the main issue is the same as Newark....at normal capacity it would be just too busy of a place. Even a crowded restaurant is tolerable because once the adjoining tables are seated the only people walking by you are the employees. At Sawgrass its a constant. I think they need to somehow create a separation from places where you eat from where people walk. Maybe a half wall or a wood screener (

I also think they need to settle on the purpose of Sawgrass. Right now its a proshop, a mini vegetable shop, and a place to eat and drink. If they all have to remain, wall off the Proshop and Grow with a separate entrance. Make the bar larger with more seating. As others have mentioned better seats.
