Here are a couple of suggestions.
The Mill - A bit pricey but very good food and drinks in a nice atmosphere. They don't make beer.
Sensational dining at one of Hershey's best restaurants with scratch-made dishes & craft cocktails with dinner and weekend brunch.

Englewood - A brew room and an event space. The menu is very limited but it's all good. Tonight's event is a Grateful Dead Tribute.
Here is the main site:
The Englewood is a historic Hershey, PA originally built in 1861, restored into a venue that hosts wedding, private events, and live concerts. Our state of the art venue includes a stage with professional audio, lighting, and image projection, as well as private quarters perfect for smaller parties

Troegs Brewery - I like this place. There food though is very expensive for what you get but it's fun to go there.
Founded in central Pennsylvania in 1996, Tröegs is a brewery for people with a sense of adventure and curiosity.

The Boro - A local sports bar with good food and great prices. The link I found only references their Harrisburg location. I much prefer the Hummelstown location. Here is the address:
401 E Main St, Hummelstown, PA 17036
