You didn't get into this for spreadsheets. But the spreadsheets are where the money hides.

25 years of food cost lessons, kitchen ops, and menu math — from food kiosks to four-star dining rooms. No consultant-speak. Just the numbers that actually move the needle.

Joe Hertel — 25 years, every position, every format

About Joe

25 years in food and beverage. I've worked and managed every position — from food kiosks and mid-mountain ski restaurants to banquets for a thousand people, four-star dining rooms, alpine club members-only service, golf courses, food courts, resorts, and a $5M private restaurant where I was GM. Every format this industry has, I've run the kitchen and owned the P&L.

I'm an operations obsessive. When I walk into a restaurant, I'm not eating — I'm watching the back of the house. I want to see their systems. Spoodles or ladles? Portion cups or eyeballing? Lexans labeled or chaos? The same dish served a thousand different ways because of one small difference in how a kitchen runs. I'm always hunting for the best food and the best concepts, and I can't stop looking at how they got there.

Here's what I love about this work: you show up every day with the outline, but you never know how it's going to fill in. The truck is late. The walk-in compressor is down. Your best cook called out. A party of 40 walks in unannounced. That's not chaos — that's the job. I love the challenge of figuring it out while managing the guests, the staff, the owners, and being fiscally responsible for all of it.

Every owner I've ever worked with had the same good intentions — update the recipe cards, run the real numbers, fix the pricing. But the line needs you and the phone is ringing and the Sysco rep is early, and it never gets done. I built this because I kept seeing that pattern. The same $3,000 hiding in recipe cards nobody checked. The same menu items bleeding money while everyone thought they were winners. I see those connections and I can't not build the fix. That's what this journal is — the patterns I've spotted across 25 years, the systems that actually work, and the numbers that tell you where your money is really going.

How I Organize What I Know
Samin Nosrat taught us every dish comes down to salt, fat, acid, and heat. Turns out, so does every restaurant decision. Here's how I sort 25 years of lessons.

Joe Hertel May 28, 2026 Food Cost

Every point is a thousand dollars. You’re probably losing five.

At a million in revenue, every food cost percentage point is $10,000 a year. Most operators are running 3–5 points hotter than they think. That’s $50,000 walking out the back door.

$30K–$50K/year — leaking in ounces, invoices, and drift

“I ran a property at what I thought was 31%. When I actually costed every card, I was at 34.2%. That’s $32,000 a year I was telling myself didn’t exist.”

Joe Hertel May 27, 2026 Field Note

I costed every recipe card in January. By June, every one of them was wrong.

Chicken Parm: $4.81 in January, $5.73 in June. Ninety-two cents a plate, invisible for five months. The recipe didn’t change. The prices did.

$6,133/year — hidden in recipe cards nobody updated

“I sat down with the Chicken Parm card and the latest Sysco invoice. The card said $4.81. The invoice said $5.73. Five months of not looking.”

Your “best” food cost percentage is costing you $14,000 a year.

Two restaurants. Same menu. One runs 28% food cost, the other runs 34%. The one at 34% makes $14,000 more per year. Contribution margin beats percentage every time.

+$13,728/year — from the “worse” food cost

“I chased food cost percentage for years. I was optimizing the wrong number.”

Every item on your menu falls into one of four buckets. Most owners have never looked.

Your bestseller might be your worst performer. I spent six months looking at one food cost number for the whole menu. That number hid everything.

$2,890/month in margin erosion — from just 3 items nobody questioned

“Your gut already knows which dishes should stay and which should go. The matrix just proves it — and shows you the dollar amount you’re leaving on the table.”

Be the Standard — The Restaurant They Compare Everyone Else To

There's a place in Holland, Michigan called Kozak's. They make one thing so well that they've ruined every other gyro I've ever had.

$10,000+/year — one loyal guest who chose you as their standard

“You know you've made it when your regulars stop telling people about you. They keep you as their secret because they're afraid they'll lose their table.”

Your bar used to cover for your kitchen. It doesn't anymore.

By Joe Hertel | May 7, 2026 Here's the number that should keep you up tonight: $37,800. That's how much net profit disappears from a $1.5 million restaurant when beverage sales drop from 30% of revenue to 22% and food cost drifts just two points.

$37,800 in net profit — gone when beverage drops from 30% to 22%

“I didn't figure this out at a conference. I figured it out staring at a P&L that didn't make sense anymore.”

I watched our best-selling dish bleed money for six months. I was the problem.

The Steak Frites was the best seller at a restaurant I managed. Every Friday, every Saturday, sometimes thirty covers in a single dinner service. It was also quietly bleeding us dry.

$3,800/year — recovered with a $15 scale and a printed card

“My cooks weren't sloppy. I was. I never gave them a spec to hit. The eyeball method drifted two ounces north and I didn't catch it for half a year.”

There's a date on my whiteboard circled in red. If nobody pays by then, I'm done.

> Entry: J-006 | Source: DEC-010 (Pieter Levels, 607 citations) > Platforms: Reddit r/Entrepreneur, r/SaaS, LinkedIn On the whiteboard in my office, underneath the roadmap and the lead list and a sticky note that says "SHIP OR DIE," there's a date circled in red marker.

60 days. Revenue or nothing.

“I know three guys building software right now. Two have been 'almost ready to launch' for fourteen months. Zero have revenue. I refuse to be the fourth.”
