Tyber Creek is a great example of a risk-reward type of place.
You definitely run the risk of the following: drunk idiots who are all wearing the same thing (polo shirts and khakis or plaid shorts), a crowded bar, and the potential to lose your voice talking to the people you are with due to the LOUDNESS of the place, both downstairs and upstairs where DJs and bands play.
I also enjoy the outside area, which is where I like to head when the weather is nice.
If you can handle all of that, you are likely to enjoy yourself, as there is good music, $2 Guinness draughts, and a great place to observe funny drunken behavior.
Definitely a younger clientele, similar to that of Angry Ale's. Not the type of place I want to frequent, but an amusing and sometimes fun place to hit up every now and then.
