Courtesy Diner

Courtesy Diner is only a few minutes from the zoo and park, easy to get to. Parking here is in front and fine, although when it gets packed inside it can be tough to park. Inside they have probably a dozen tables along with a few counter top seats. Their menu isn't massive but pricing is decent for portion size. The food is good, both breakfast and lunch items, including the western BBQ burger. The staff are so nice, but when they get busy it can take a bit to get food since it's cooked fresh, so be patient. Overall it's a great place to eat, and it's cash only so be prepared (although they have an ATM still).

We have been frequent customers of the Courtesy Diner for many many years. The best "hole-in-the-wall" diner in St. Louis, IMHO. Our go-to one was on S. Kingshighway, but that one has since closed. Over the years, my wife and I have tried pretty much all that they have to offer on the menu. My favorite has always been the Slinger. Such a strange combination of flavors, but so tasty! It'll definitely fill you up. Their burgers, Chili Mac, regular breakfast items, everything is just amazing! The staff is always friendly and accommodating. The restaurant is clean (unless during a rush. Then the floor can get a bit messy. They're quick to come in with a sweep after a table leaves, though. On top of it!) Though we no longer live in STL, this restaurant is a must when we are in town. The prices are very reasonable and the portion sizes are great. Can't wait to go back and devour another slinger. Side note: Cash Only... but they do have an ATM on site.

Sat for almost 10 minutes being ignored by every waitress here. Watched them, serve 3 people who came in after me and had to ask for someone to please take my order. I won’t be back and thank you for the racism for breakfast. #beingblackinamerica

Great for breakfast. Busy on weekends. Cash only. Reasonably priced.

Always used to go here late night for burgers and breakfast. Classic diner. We’ve had good food and good service, especially given the late hour. It is not fine dining but it is a classic diner experience. Being in the city, it draws an eclectic crowd. The jukebox is a classic touch as well. For some reason, dozens of people seem to play Ring of Fire if they are here late night.

Really neat little diner with an old-school feel. Very good prices - the food is simple and nothing fancy, but the service is fast and friendly. Lots of bar seating, but there are also a few booths (some didn't look clean, so I opted for the bar). Bring cash, and to-go orders have an added gratuity. I visited St. Louis and tried a slinger for the first time - I don't have anything to compare it to, but I thought theirs was very good. They have a parking lot that has a decent amount of spots.

Great food great prices. Cash only which I should have figured but they do have an ATM. I’d come back.

Great quick dining experience. Breakfast prepared fast, right in front of your face. Real people + real ingredients = good food at very reasonable prices! We visited on a Sunday morning. While the restaurant was crowded - we were seated and served quickly.
