Being gluten intolerant, I was a little apprehensive about ordering a burger here (sans the bun). The staff was very accommodating and convinced me I could have the Black Watch burger gluten-free. Sweet goodness. They make some mean burgers here. The medium rare patty coupled with aioli sauce, smoked bacon, and an egg to top it off, was delicious. I finished my burger, which is saying a lot cause it was HUGE (especially for a small 5'3" woman). Might've been overkill, but no regrets here.
My friend loved her shepherd's pie. She still talks about it too this day (it has been a month) and wants to go back.
The service here was excellent. The waiters were extremely friendly and hardworking. We were impressed.
If you are ever in Pittsburgh, go to Piper's Pub.
