As a former Tremont dweller this was one of my favorite places. I have never had their food but it was always the first place to hit on the pub crawl. The decor is just like the name says-Treehouse with a story size parrot on the back patio. The patio is huge! Great for large groups in the warmer weather season. I say season because it can be 80 degrees in March in Ohio and 15 the next day.
They have decent draft beers including Guinness. The service is always good and the bar fits the neighborhood. Try it out the next time you are in the area!
