I love Philly Cheese steaks and I've had them at every joint in Central PA. Shugar's is the best, hands down! They have the original cheese steak with Cheese Whiz w/or w/o onions. You can get sauce and additional toppings and substitute Provolone for Cheese Whiz.. In my opinion this sandwich needs no sauce.
They have two sizes 1/2 and whole but don't be deceived; the half size could make two meals or be shared by 2. I think the price for a 1/2 is about $7.50 or so. You can also get it with extra meat. If you doubt my rave review try one.
BTW their other subs especially the Roast Beef and Provolone are excellent!
