This is quickly becoming my new "cheers." I live about a block away and it's become a nice meeting space.
The food is always delicious and pretty high-quality/fresh. I don't like mussels- but I've heard these are some of the best in Pittsburgh. Otherwise the menu doesn't change, and there is nothing unique here. Don't expect to have your mind blown, but do expect to have a good meal (I love their salmon salad). There poutine is great as are the flatbreads.
The drinks and cocktails are solid and reasonably priced. Decent wine selection and rotating beers. Once again they are your standard cocktails and nothing will blow your mind, but that's not always a bad thing.
The ambience is usually awesome too it's fairly quiet and they have a decent sized bar to sit and visit at. I've never had bad service, and they are always friendly.
