I just went to Bob's today for the first time, I can't believe I haven't been there before, the place is amazing. I need to try the steak tips and turkey tips next. The meatball sub (with provolone and plenty of sauce) was HUGE for 5 dollars and very good, though the meatballs aren't the best ones I've ever had.
The store is great! If you haven't been, go soon. Bob's is on 324 Main St. in Medford
