The Workhorse is a pub over on North Loop up from Hyde Park. It was formerly a place Scott Biram would play for tips as a one man band, called The Parlor.
The place is open until midnight, so I recommend it as a day drinking spot, and its affordable. "Happy hour starts when you get here" says the sign by the register, meaning that three dollar pints are to be had from open til close.
This neighborhood bar brings twenty to thirty something's, and you'll like being able to walk past a kitchen that's in plain view and clean; its notable that the bathrooms are as well.
In closing you'll find the clientele friendly and kickback worthy, so enjoy the pub: You will find it more than worthwhile.
