Session House
Session House is the ultimate Irish bar with a modern vibe and a pretty impressive drink menu. With so many options to choose from you'll probably get hungry, so it's a good thing that they're also known for their bar food (they had us at buffalo chicken nachos). On that note the portions are big, so bring all of your colleagues for a sharing happy hour.
