The food is standard pub fare -- greasy and, for the most part, tasty enough. The pretzel stick starters were better than anything else we ate.
The atmosphere is decent, but the service was the worst I've had in a long time. I only get back to Pittsburgh 6 or 7 times a year from Colorado and like to find a place to take my kids out to dinner and I've taken them to Sieb's before, but never experienced service this bad. It's never been great, mind you, but not so bad that I had been tempted to not give a tip.
The waitress was pathetic. My 3 year old grandson was with us and she didn't make any effort to accommodate his needs. She didn't even pretend to care whether or not we were having an enjoyable experience.
I'll never take my family here again and be warned, this is definitely not a kid friendly restaurant.
