I am aware that this board is probably tired of hearing about Wegmans, but it just had to be announced that the new store in Fairfax (near the Government Center) is open. I missed the "official" opening at 7am, but by the time I got there (around 7:30) the parking lot was virtually full and the aisles inside were nearing gridlock conditions.
One thing that was initially confusing about this location is that it appeared that they had only a very small wine department. I was very disappointed about this, since the Dulles store has a pretty wide assortment. But fear not! It turns out that the wine dept is downstairs (enter through a separate entrance in the lower level of the parking lot, or by elevator/stairs in the left-hand front corner of the main level of the store). And this wine dept seems to be larger than the one at Dulles, and it has its own check-out, so if you need to pop in for a bottle on your way to a party, it should be quite convenient.
Otherwise, this store seems pretty similar to the Dulles location.
