Legacy Village is this strange sort of outdoor mall shopping area. Now I live in Buffalo, NY and I can only assume that Cleveland winters are not all that great. I do not think I would want to be here when it is snowing. In any case, my mom and I usually make this our last stop to walk around and get food before heading back to WNY when we come for the day.
The stores have changed over the years, and there are few empty spots now. Some higher end boutiques, specialty brands like BOSE, Le Creuset, chains like White House Black Market, Dick's Sporting Goods, and such. We usually tour around Crate and Barrel (was helpful last year when my mom was considering furniture option) and Arhaus (but they don't like the browsing as much. Got asked 3 times by same guy what we were looking for. Calm down!).
They have a nice large Pier 1 here now, and Nordstrom Rack was quite expansive. Unless you are looking for something specific, there are probably a lot of stores you might skip or not have any interest in.
There are a lot of different restaurants, but mainly sit down places so it isn't like a food court setting, but there are patios at many of the restaurants and a central grassy court if kids need to run off a little energy. We usually go to Stir Crazy and it is usually quite busy even later on a Monday/Tuesday evening. Most things are typical of a shopping center eats (5 are same as ones our big mall area in Buffalo).
