I've been to Sidelines several times now, as it's nearer to the side of town where my family lives. It's also one of the only bars in the area in which your vision isn't completely obscured by a haze of smoke and bad beer. Yes it's a sporty dive bar, but it's really clean, the food and drink options are insanely good, and the service is always friendly. I'm a fan.
Sidelines is owned by the same people who run the Swickley location as well as the wonderful Fireside Public House in East Liberty. This is evident from the menu full of well-executed, quality food and deep beer list with plenty of options to suit every taste. The prices are reasonable for any time of day, however happy hour is where it's at! It's 4:00-6:00 seven days a week. Recently I went on a Sunday afternoon with my boyfriend and two of my siblings, and there was a generous wing special as well as half off all drafts under 7% abv. Everyone raved about the wings, and I lost count of how many drafts I ended up with for less than $15.
Overall I really appreciate the care and attention that goes into making a place like Sidelines nice. It's a real gem and far from a standard dive bar. Since I just joined their beer club, I pretty much have to keep coming back...oh well :-)
