My boyfriend and I were on the hunt for grass fed burgers in Pittsburgh when we discovered Habitat. It's not the cheapest place, but the menu ingredients are locally sourced and I imagine the overhead at the Fairmont Hotel is pricey.
We biked over there one day in early spring, arriving hot and sweaty, and ready to get our burger on. We did not feel uncomfortable in our street clothes, despite the fancy atmosphere. We sat at the bar and had a pleasant conversation with the guests sitting next to us who were visiting from NY (we just moved here from Brooklyn and found we had a lot to talk about).
We couldn't resist a few small plates before we moved on to our burgers. We shared the chilled english pea soup that went nicely with a glass of rose as well as a beet salad with goat cheese, wild honey, and coriander. Everything tasted fresh and loved!
Our burgers were a special treat for us. Cooked just as we requested on a lightly toasted brioche bun with Pennsylvania cheddar cheese and all the fixings. Plus, the fries were perfectly seasoned and HOT! My only complaint is that they did not have homemade mustard, only Dijon.
We've been back several times now. We recently tried the Spring risotto, which was also cooked perfectly. We hope to expand our selection in the future, but the burgers are just so tasty.
