Born at the 1982 World’s Fair in Knoxville, Tennessee, the Petro, a layered delight of Fritos corn chips, special recipe chili (also available plant-based), shredded cheese, diced tomatoes, real sour cream, green onions, black olives and jalapeños quickly became a fan-favorite! Premium toppings such as grilled chicken, pulled pork, guacamole, salsa, queso, buffalo or bbq sauce make for a Premium Petro’s Experience. The menu rounds out with giant baked potatoes, black angus all-beef hot dogs, nachos and wedge salads, all made to order to your specifications. Last, but certainly not least, is the refreshing Hint-of-Orange Iced Tea (not flavored, but infused with orange essential oils and brewed with dried orange rind), the perfect compliment!

Our family has had 2 horrible dining experiences with them in the last couple of months. Their dining room is not open as Google says. Just today, went through the drive-thru to use a Knox Co school coupon book coupon for a buy one get one free with purchase of drink. Wanted 2 large Petros but the employee said they wouldn’t honor it for large sizes, only small. That is not on the coupon. They also didn’t put the chips on the side so had to drive back through the drive thru to get them. The food is fine, but save yourself time and headache and go to a different location. We will not be going back and will be telling everyone we know not to give them business.

I didn’t have great experience here. Went through the drive thru. Not busy and I was the only car in line. Not a complicated order. Just the original chili bowl with no black olives. Asked twice for no black olives. Get to the window and there is a tip jar with sign “tips are appreciated.” Ok, not sure what I’m supposed to be tipping for at a drive through. You guessed it, get home and my chili is covered in black olives. Another business crossed off my list.

Great service with nice workers. We ate inside, although this place is mainly for driving through. Petro’s is a classic and it’s really awesome that they do catering now. It’s hard to believe that they’ve been in business since 1985 and longer. I am never disappointed. Like I mentioned though, I give them a 4 star review since the dining area wasn’t great. But, they’re a drive through place. So, don’t expect wonders inside.

The food was okay but the staff was friendly. They basically sell chili bowls, nachos, hot dogs, and baked potatoes. I really liked the fact that they offer vegetarian chili and chicken chili. My daughter got her food with vegetarian chili, I got chicken chili, and my husband got regular chili.

I am very sad I didn’t receive the queso dip and ONLY chips which I ordered tonight. This is the main reason I came to your restaurant. After calling the restaurant multiple times to discuss…all I got was a hang up.

The entire staff was awesome and the wait for your food was extremely minimal. The entire place was very clean to include the restrooms. I’d recommend this place to everyone. Incredibly awesome experience.

A Knoxville staple, I have to come here on my travels though my hometown. It’s a simple concept, the frito pie, attempted in many places. Petros is a great value, a great product, and decent service. Also the hint of orange Tea is a muuuuuust.

Good experience. Quality food. Loved driving through so that I could get a happy smile from the employees. The nice young man that was at the window last time I went was named Scott. Scott gave me such pleasant manners and made my time at the window a pleasant time. He is the example of a model employee. He told me to have a petros day and now I tell all my friends the same. I love this young man. Food was good too.
