Failte's is one of Mississauga's "hot spots" for a casual night out.
Really though, it's hit or miss. On weekends it gets fairly busy, so you may have to wait in line, and cover is $3. The ambiance inside is not the best, it's the classic old-looking wood and exposed brick Irish pub. I do like that there are lot's of different rooms though, which means you can move around to alter your experience. They also have some booths tucked into various nooks and crannies if you're looking for something private. They have a good outdoor option as well- there's an upper deck that's well protected for those chilly nights and then a large lower patio.
Failte's has live music and this can be a great addition to your night or an absolute headache. There's a very small dance floor in front of the stage so you can get up and groove if the mood hits you, but it tends to be more of a sit (or stand) and listen atmosphere.
Failte's has a very random crowd. The age range here is huge- from those freshly ID'd youngsters to fairly old (sometimes creepy) men. There's a large variety of people who frequent Failte's- hipster, cougars, jocks etc. There's not really a "mix and mingle" vibe here, so you definitely want to bring a good group along and make your own fun!
