Fair Enough

"When you see the owner breaking apart frozen chicken on the curb outback."

High Humidity

"High humidity inside."

- Presitigious_Gold_585

"Yes! The small that causes is unmistakable."

Sticky Furniture

"All of the furniture and menus are weirdly sticky..."

- Silver_Sunshine360

"I know what *some* of that is. Some furniture and cleaning solutions aren't compatible. The cleaning spray reacts with the finish on the table tops, and softens, it, which makes it feel a bit sticky, and dulls it super fast... but it's the sanitizer cleaner they use for *everything*, and they don't want to have to deal with a separate cleaner for certain surfaces."

"I used to sell commercial office furniture, and we'd run into this issue sometimes. The worst was when a company asked us to source some tables they found from a local craftsman (since we were already an approved vendor in their system, they often had us buy and deliver stuff for them). Beautiful, hand-made stuff."

"So we bought them and arranged for the delivery and placement. When we got to the site and saw where they wanted them, I cringed... I knew the tables were finished in shellac, and they were having us put them in their lounge area, where I knew they often had events with drinks."

"Shellac dissolves in alcohol. Spilling a drink on it can ruin the finish. Before we left, I left a note on the tables about being careful and emailed the client some care tips. The NEXT DAY they sent us pictures of the ruined finish, asking, 'What is wrong with our tables?!'"

Sounds Fishy

"A seafood restaurant should NOT smell fishy."

- turtyurt

"And conversely, a seafood MARKET that does not smell fishy is indeed fishy."

- FourMeterRabbit

A Specific Smell

"That *smell.*"

"You know the one. floors feel a little slippery/slimy underfoot and it smells like they've been mopping the place with the same dirty mop and bucket water for weeks."

"This isn't something you're likely to see in a nice place but I've encountered it in more fast-casual dining places than I care to remember."

- y2knole

"THAT smell. It always reminds me of yeast rolls. I guess it's bacteria in the mop water that has been setting in that bucket for three days."

- SpeelingChamp

Restroom Cleanliness

"Dirty restrooms."

- carboncanyondesign

"This is a dead giveaway. If they can't keep part of the restaurant that the public DOES see clean, you can imagine how the non-public facing parts look."

- OkaySureBye

"Health inspector here. The key is to look for build-up that looks like it's been there more than a day. Most places don't have bathroom attendants and it's unrealistic to expect public bathrooms to be spotless every minute of the day."

The Right Audience

"Whenever I have friends come to visit me in Osaka and they're dying to try some authentic ramen. My goto line is:"

"'Look for the most run-down looking, back ally shack you can, the more run-down looking; the better. Guaranteed It'll be the best ramen you'll ever have!'"

"And to anyone who happens to read this, no, Ichiran is NOT the best reman joint. It's nice don't get me wrong but please ask around, research ramen in the area you're visiting, I guarantee you there's SO much better out there!"

- kevo998

"I look for people of that ethnicity eating there. Mexican restaurant with only white people? It might be good. Mexican restaurant with Mexicans wearing high-vis shirts? S**t's going be fire. Bonus points if there’s a grocery store attached."

"The same thing goes for Asian restaurants sans the high-vis shirts."

- PsychoticMessiah

Too Many Variables

"A huge menu."

- dnb_4eva

"A huge VARIED menu."

"Places like Chinese, Mexican, and Indian restaurants generally have large menus, but most items use the same base ingredients."

"It's the places that try to incorporate lots of wildly different dishes that you want to avoid."

- MagnusPI

Unexpected Restaurant Guests

"A raccoon falling through the ceiling tiles. 1:00 AM, drunk as h**l, looking for something to eat, and I found a dive that was still open. I ordered my food, and while waiting for my order, a raccoon fell from the ceiling."

"The waitress ran to the back screaming. The cook came out armed with a cleaver and chased it into the kitchen. The look on his face was like it had happened before. Other people eating there were in shock and got up and left."

"Mystery meat: the new special. Get me the f**k out of there."

- alwaystired707

That Wait Time

"I immediately look to see if there is anyone actually eating. If there are a half dozen tables with no food on them, and people looking anxiously to the kitchen, I'm out."

- scotttr3b

Cleaning Response Time

"Multiple dirty tables that haven’t been cleared. If the restaurant isn’t crowded, staff should have time to clean them. If it is crowded, staff should be trying to turn tables over quickly."

"Dirty tables mean they are either severely understaffed or the staff just doesn’t care. Either way, you will be waiting a long time."

- 787la57la47al

Inappropriate Smells

"Once went into a restaurant that boasted the biggest Cinnamon Rolls in the city/state... Only for there to be a pervasive smell of absolutely raw stagnate sewage throughout the dining room. Needless to say, did not return."

- nekroves

Construction Said It Best

"A green flag for a restaurant is when you see a lot of construction workers going there for lunch. You'll know it's cheap and good, hearty food."

"In my old city, there was this tiny little family-owned Chinese restaurant with delicious and cheap lunch specials. Every construction worker downtown sat at the counter at the front for lunch."

"Meanwhile, the waiters would be in this little back room watching TV and the chef must have been at least 70 years old. The food was genuinely so delicious and filling. Probably not good for your cholesterol but so tasty!"

- okaymoose

Atmosphere Matters

"Not a red flag about the food but if a place has their music up so loud I can’t hear the person I’m with, then I won’t eat there."

- Adro87

"Conversely, if it's TOO quiet; as in, not only is the sound system way too low, but if the customers are also weirdly quiet (barely having conversations, just sort of sitting there) and the atmosphere seems almost stifling."

"A couple of years ago we walked into a gastropub in Scotland just like this - very low music, the room was half full (and this was at peak lunch time), and everyone who was there were just sitting, looking sullen, barely speaking, waiting for their food. Just really... odd... vibes."

"After five minutes of sitting at the bar trying to get the attention of staff (who were all standing around looking at their phones), we left and went to a definitely *not fancy* cafe down the block that was the absolutely opposite: people just seemed happy to be there, staff were attentive, and the vibe was really welcoming."

The Ultimate Red Flag

"Gordon Ramsey walking in with a camera crew."

- Tint-kicker

"One of the local restaurants we like was recently closed for a bit due to filming for 'Kitchen Nightmares.'"

"My husband still likes to get their food, but I'm waiting until the episode airs!"

- Lington

No restaurant is going to be perfect 100 percent of the time. They're going to have a slow night or poor response time or get some orders wrong from time to time.

But there are far more problematic behaviors and characteristics to find in a restaurant that are perfectly good reasons to never go back there again, no matter how good they may have been in the past.
