Living in Bellevue we don't have many restaurants I like to frequent for dinner. Vivo was always a little too expensive to go to too often so I've been delighted with Bite Bistro.
In my opinion there might not be a better value in all of Pittsburgh. Their food is inventive and after going there several times I've never had a bad experience or been anything but thrilled with my food.
There are plenty of Vegetarian options, and the deserts are always delicious and something I've never tried before (cereal milk panacotta and corn gelatto were both amazing).
Since Bellvue is dry, it's BYOB, but the corkage fee is only $2. Bite Bistro is one of my favorite restaurants in Pittsburgh, and definitely my favorite that I can walk to.
