I visited last weekend for a quick lunch with my friends and ordered the Buckineer burger. It was so good that I had to savor every bite. The service matched the laid-back diner vibe, and our food came out right on time. The building is on the smaller side, so seating could feel a bit tight when it’s busy, but there are two drive-through lanes if you prefer that. The staff were super nice, the cashier even complimented my friend’s debit card sticker and gave him a coupon, which made our visit feel really welcoming. I was also happy with the prices because everything I ordered was worth it. For under $12, I got a burger, fries, and a root beer float, a deal you don’t see often anymore. I’ll definitely be coming back soon and recommend Gem In & Out to anyone looking for great food and a relaxed local atmosphere.

It's Spring Break for my kids, so I grabbed Gem In & Out for their lunch! Very busy even for a Tuesday, so I opted to go inside instead of the drive-thru. The service was super friendly and very quick! I only waited in the dining area for a few minutes. The VALUE is insane! I ordered the special (promoted on their roadside sign): 5 burgers & 2 large orders of fries for $19.99. My kids annihilated it! For myself, I ordered a grilled chicken wrap: spicy, with ranch. It was absolutely scrumptious, with the perfect ratio of chicken, lettuce, cheese, and sauces.

Had the best time with my 3 kids and my parents. The work staff were very nice and accommodating (not getting annoyed when you ask for sauce like most people do). My kids loved the inside and all the pictures. My kids were treated well instead of badly which people now a days are rude to kids. The food was good yum yum

Wow. Wasn’t expecting much - food was priced very low… but boy was I wrong. The food was delicious! The service was fast and the employees were very kind! I was there from out of town and told everyone I could about how impressed I was with this place. Hope to be able to visit the area again and this place will be on my list to eat!
