Boomers linger for conversation and Caesar salad; Gen Z taps, tastes, and posts before the first bite.

A packed brunch spot on a Sunday morning is one of the few places where four generations jostle for the same omelet.

Watch closely, though, and you’ll spot two very different rule-books playing out at every table: one belonging to boomers, the other to Gen Z.

Their choices—menus, money, even how long they linger—reveal far more than quirky habits; they expose the deeper values driving each generation.

Below are the ten restaurant moves where the contrast is loudest and what those moves say about the mind-sets behind them.

1. Menus: paper vs QR codes

Remember when opening a menu felt like wrestling a short novel? Boomers still love that tactile moment.

Gen Z, on the other hand, taps the little black-and-white square without blinking. As Datassential’s 2024 FoodBytes survey put it, “68% of Gen Z happily scan QR codes at restaurants, compared with just 22 % of boomers.”

What it says about values:

Boomers—Comfort & habit.* Paper equals reliability; it’s how they learned to order and they see no reason to change.

Gen Z—Efficiency & hygiene.* A phone is faster, cleaner, and updates in real time—core perks for a cohort raised on software updates.

I’ve mentioned this before but the quickest way to make my twenty-year-old cousin sigh is to hand him a tri-fold menu that smudges ketchup on his fingers.

2. Ordering style: server chat vs silent tapping

Boomers strike up conversation—“What’s your favorite dish?”—treating servers as trusted guides. Gen Z often builds the order digitally before the water arrives, customizing everything from spice level to the number of ice cubes.

Values at play:

Boomers—Relationship.* Growing up when personal service was king, they see small talk as respect.

Gen Z—Control.* Apps let them tweak without verbal back-and-forth, sparing anxiety and mistakes.

On a recent trip to Tokyo, my boomer dad kept charming waiters with his two words of Japanese while my Gen Z travel buddy quietly built the same meal on his phone—no pronunciation panic required.

3. Dietary focus: steakhouse staples vs plant-powered plates

Boomers often default to “the usual”—prime rib, Caesar salad, butter on everything. Gen Z recites questions about oat-milk béchamel and jackfruit carnitas before the bread hits the table.

Values revealed:

Boomers—Tradition & flavor memory.* Their palate is anchored in comfort foods that evoke home.

Gen Z—Ethics & experimentation.* Climate change headlines and TikTok recipe hacks prime them to treat every meal as a micro-vote for sustainability and curiosity.

I once watched a boomer couple swap entrees mid-bite because “she always orders better,” while the Gen Zers next to us ran a taste test between three house-made nut cheeses just to pick a favorite for Instagram.

4. Trying new places: loyalty vs curiosity

Data from TouchBistro’s 2024 Gen Z Diner Trends Report shows that 27 % of Gen Z visit a new restaurant several times per week, while exactly 0 % of boomers report doing so.

Value signal:

Boomers—Consistency.* They return to spots where they “know the owner” and the decaf is strong.

Gen Z—Novelty as status.* New equals shareable, and shareable equals social currency.

When I suggested a Cambodian pop-up to my boomer aunt, she countered with “Why mess with Earl’s Diner? Earl knows my order.” My Gen Z cousin? Already scanning the pop-up’s menu on their phone.

5. Pace of the meal: lingering vs literal fast-casual

Boomers treat dining like theater—courses in acts, conversation the soundtrack. Gen Z, squeezed by side hustles and doom-scrolling, gravitates to formats promising food in ten minutes or less.

Values behind the clock:

Boomers—Presence.* Mealtime is a ritual to slow down.

Gen Z—Productivity & spontaneity.* They’d rather repurpose the hour for content creation or a second hangout.

6. Money talk: picking up the tab vs splitting to the cent

Boomers often default to “I’ve got this,” viewing generosity as a sign of good manners. Gen Z whips out Venmo before dessert, determined that everyone pays their exact share—tax and tip calculated automatically.

A server in Austin recently watched a table of four Gen Z friends transfer seven micro-payments before her handheld even printed the receipt.

She told me—half amused, half exasperated—that boomers are “way more likely to just throw down a card.”

7. Tipping: tradition vs algorithm

A nationwide 2025 poll of 2,005 Americans found boomers tipping an average of 16.4 %—the lowest of any generation—while Gen Z leaves 19.3 % on average.

What that means:

Boomers—Fixed rules.* They stick to the 15-to-20 % guideline they learned decades ago.

Gen Z—Contextual generosity.* The preset prompts on a tablet nudge them higher, especially if service workers share wage struggles on social media.

8. Photo etiquette: memories vs marketing

Boomers snap one obligatory family shot, then stash the phone. Gen Z stages flat-lays, adjusts natural light, and records the cheese pull in slow-mo—free marketing for the restaurant, of course.

Deeper layer:

Boomers—Experience first.* Phones are secondary.

Gen Z—Identity broadcast.* The meal isn’t over until it’s archived on Stories.

9. Payment tech: chip cards vs mobile wallets

Tap-to-pay still feels futuristic to some boomers; physical credit cards remain the comfort zone. Gen Z arms their phone with Apple Pay, Google Pay, and whatever crypto debit card gains cash-back on lattes this month.

Value clue:

Boomers—Security.* Swiping a tangible card feels safer.

Gen Z—Seamlessness.* They expect frictionless checkout everywhere, restaurants included.

10. Sustainability lens: optional vs essential

When the check comes in a plastic folio, boomers rarely notice. Gen Z, raised on climate anxiety, clocks single-use anything. They’ll ask about compostable take-out containers before committing to dessert.

Underlying priority:

Boomers—Practicality.* “Does it work?” ends the discussion.

Gen Z—Planet stewardship.* Every bite is tied to a bigger ecological narrative.

The takeaway

The next time you’re people-watching over noodles, pay attention to those little generational tells.

They’re not just dining quirks—they’re windows into how each cohort sees the world: boomers through the lens of stability and relationships, Gen Z through speed, customization, and cause.

Neither is “right,” but understanding both equips us to order (and live) with a little more empathy—and maybe tip like the best version of ourselves.
