Korean restaurant owners get pitched online ordering platforms every week. The pitch decks all sound similar; the actual fee structures are wildly different. After helping 18 Korean-American restaurants integrate online ordering across the major platforms in 2025–2026, we have a clear-eyed view of which platform fits which restaurant. Spoiler: there is no single best answer, and the wrong choice can cost you 8–15% of every order in fees you did not need to pay.
The five platforms Korean restaurants actually use
Toast — full POS + online ordering integrated. Around 2.49% + 15¢ per card transaction, $89/month base, online ordering native at no commission to Toast. ChowNow — order-only, no POS. Flat $149/month, no commission per order, restaurant keeps 100% above the flat fee. Square — POS + online ordering, 2.6% + 10¢ in person, 2.9% + 30¢ online, no monthly fee on free tier, $29/month for branded online ordering. UberEats — 30% commission per order on delivery, around 6% on pickup-only, no monthly fee. DoorDash — same structure as UberEats roughly, 15–30% depending on plan. Custom (built into your own website) — 2.9% + 30¢ in Stripe fees, no commission, but $4K–$10K upfront build cost.
When Toast wins
Toast is the right pick for Korean BBQ steakhouse-style restaurants, fast-casual concepts above $1.5M annual revenue, and any Korean restaurant that wants integrated front-of-house POS plus online ordering plus kitchen display system in one package. The math: Toast's native online ordering has zero commission per order (only the standard card processing fee), so a restaurant doing $30K/month in online orders pays Toast roughly $89/month + $750 in card fees vs giving DoorDash $9,000 in commission. Toast wins on volume.
When ChowNow wins
ChowNow is the right pick for medium-volume Korean restaurants ($25K–$80K/month online ordering) that already have a working POS they like. The flat $149/month with zero per-order commission means every dollar above ~$5,000/month in online sales is pure margin retention compared to delivery marketplaces. ChowNow integrates with most major POS systems (Toast, Square, Clover, Revel) and most importantly puts the orders on YOUR website, not a marketplace where customers can switch to a competitor.
When Square wins
Square is the right pick for new Korean restaurants under $40K/month total revenue, café-style or fast-casual concepts with simple menu structures, and owner-operators who want one platform without paying a monthly fee until volume justifies it. Square Online (free tier) gives you a basic ordering site with branding limitations. Square for Restaurants ($29/month) adds the customizations needed for menu modifiers, dietary tags, and Menu schema integration. For most Korean cafés and casual restaurants under $1M annual revenue, Square is the cheapest reasonable starting point.
When marketplace delivery (UberEats, DoorDash) wins
Honestly, for new restaurants only — and even then strategically. The 30% commission is brutal margin damage. Run UberEats and DoorDash for the first 6–12 months for discovery, then aggressively migrate your repeat customers to your own ordering through promo codes, in-bag inserts, and incentives. The strategic mistake we see Korean restaurant owners make is treating the marketplaces as a permanent revenue channel instead of a customer acquisition tool. By month 18 you should have 60–70% of your online order volume on your own platform, not the marketplaces.
When custom (built into your website) wins
Custom integration is right for: established Korean restaurants over $2M annual revenue, multi-location operators, restaurants where the online experience is part of the brand (think Cha Cha Matcha, Eggslut for design tier), and restaurants with complex menu logic that ChowNow or Square cannot handle. The math: $6K average build cost amortized over 24 months at $30K/month online order volume vs ChowNow ($149/month × 24 = $3,576 + $0 commission). Custom is more expensive over 2 years but gives you full design control, your own customer data, full Menu schema for SEO, and no platform lock-in.
Common mistakes Korean restaurants make with online ordering
- Running 4 platforms simultaneously (Toast online + UberEats + DoorDash + Grubhub) without consolidating — your kitchen prints from 4 tablets, staff misses orders, customer experience degrades
- Pricing the same on marketplaces and direct ordering — bury the marketplace by making your direct site $1–$3 cheaper per order; customers learn within 60 days
- Not adding Menu schema even when the platform supports it — Menu schema makes your menu items show up in Google rich results above marketplace listings
- Letting marketplaces own customer data — every restaurant should run a regular email/KakaoTalk capture with first-time direct orders to migrate them off marketplace platforms
- Charging delivery fees that look high — customers think 30% commission is your fault; they do not understand it is the marketplace. Communicate clearly: "save $4 by ordering direct"
