Sounds like you all live in VA? We are lucky to finally have a Wegmans very close to my house here in MD, but it's missing that HUGE wine section like the one I've seen in Fairfax County! Everything at Wegmans just seems larger than every other grocery store- the meat, seafood, produce, gluten free sections especially. And their cheese department is like in a world of it's own!
I think we ate dinner at Wegmans 2-3 times a week the first month it was open. I won't say it's cost effective, but there is something for everyone! Also, with the first few opening weekends, there were additional food stands for prepared foods like grilled steak and crab cake meals. I love that I can take the kids, they can get subs or pizza or whatever off the bar, and I can get sushi. The dessert section in the bakery awesome, and they even sell stuff by the slice in case you are dining in.
The one that is an hour north of me has this awesome feature where you can order your deli items on a touch screen before you go in the store, and then by the time you get to the deli, your order is already sliced and ready for you. I love that and I'm not sure why they didn't incorporate it in the one by my house. I'm a sucker for impulse buys so I tend to buy a lot there that is new and interesting that I may not have seen at other stores.
