I'm definitely a fan of Hem's. It's a cute bar/restaurant tucked in the Oakland university area. If you come here, don't expect haute cuisine or anyting too complicated. It's a bar, so expect bar-ish food.
What you SHOULD expect is: awesome drink prices/selection and an extensive half-price menu during select times. Something like, before 11am, 2-4pm, and after 9pm most things on the menu are 1/2 price. The garlic-parm wings with a side of fries is what I usually get and it's always great. I wash it down with whatever draft specials they have. They offer amazing draft specials daily ($1.50-$2.00), Yuengling pitchers for $5.50, and as other Yelper's have said, very reasonably priced PITCHERS of shots with names like Tiger Woods, Lady Gaga, and Miley Cyrus.
It gets busy on the weekends and after 9 in general. I have come before on a Friday at 9:15 and was able to find a seat at the bar no problem and get a couple of drinks in before it got crowded and all hell broke loose.
