Jimmy John's - Diamond Bar

Showed up at 9:40 and the people said it was closed as I was driving away both the guy and girl looked at eachother and started laughing so I checked and it said they close at 10pm! I had driven over 15 minutes craving their food as I am pregnant. I don?tsee anything funny of them cheating their company of customers and trying to close earlier. Hopefully someone from Corp seesthis

Great sandwiches, miss the sprouts used to put in sandwiches, adds great taste, avocados on steroids. Still a good healthy sandwich.

Best sandwiches in Diamond Bar. Amazing bread and meats. Staff is very pleasant and friendly. Store is consistently CLEAN. Huge portions and abundance of meats not like Subway.

1st time ever at Jimmy John's today. I ordered the Vito Italian submarine sandwich. I also bought some Jalapeno kettle chips. They were both delicious ????. Friendly service and quick service. I phoned my order to go. The fresh baked French bread wasperfect. I was very happy with my lunch ????

Been wanting to try them for awhile. Very clean sandwich shop in Diamond Bar. They deliver but don?t know any details about that. There?s 2 sub sandwich sizes to choose from. An 8 or 16 inch subs. The 8 inch sub was perfect for me. Other places 6 inchsubs don?t fill me up and 12 inches is too much. 8 inch hits the sweet spot. Ordered the gargantuan sub, very generous meatportions. Will come back again. If you haven?t tried them yet I would recommend. You will love the portions and flavors withtheir great tasting subs.
