Eddie's Drive in on Jefferson in Harrison Twp has great fresh burgers! I love that place, the waitresses are on rollerskates!!
A fancier burger is at JAlexanders, great burgers, the grind them fresh. Not too big, not too small.
On another note, Harrison Twp seems to be the burger place to be on Mondays, I noticed that the last few restaurants we have been to have $2.00 1/2 lb burgers on Mondays. Stiff competition!!
