Sideliner's sits is in the old "Little Athens" building on Locust street in the heart of Sewickley Village. Little Athens sut down and had another name for a while after a interior redesign.
The bar is alright... lots more seating at the bar itself than there used to be. There are lots of beers on tap, so that is good. This is also a good alternative to the Sharp Edge for six packs. The coolers along the wall are a nice addition (now that it is Sideliner's) having a much larger selection than Pizza Roma (and no smoking!) and far better prices than Sharp Edge.
The food is alright- no real complaints, but it isn't anything special. The wings are alright and most recently I had a burger there that was pretty good. I ordered it with gorgonzola, and it could have used a little more cheese. My girlfriend had a buffalo burger (cheeseburger with buffalo sauce... not a burger made from Bison) and it was alright, but it lacked some of the stronger flavors one might expect.
The prices here are maybe a little more than you'd pay for the same in the city (everything is served in plastic food baskets), but the prices are far more reasonable than most of the other places in town. This is Sewickley, afterall, so most places are upscale, and the food is really nice.
Overall this is place is alright and I would (and most-likely will) go back here.
