Seoul Café Chain — 12 Locations Standardized on JD-3

Coffee chain · Seoul, South Korea · 12 locations · Deployed 2024

Background

A Seoul-based specialty coffee chain operating 12 cafés across Gangnam, Hongdae, and surrounding districts. Each location offers freshly baked viennoiserie (croissants, kouign-amann, pastries) baked in-house on Convotherm combi ovens using 600×400 mm trays. Average baking output per shop: 80–120 trays per day.

The Challenge

The chain had grown from 4 to 12 locations over 3 years. Dishwashing practices had diverged dramatically across stores. Some shops used hand-washing exclusively; others had bought random consumer dishwashers; one had a used Hobart that didn't fit the 600×400 trays. Brand consistency was breaking down — Gangnam customers commented about cleaner pastry displays than Hongdae customers. Health inspections produced inconsistent results across stores.

The chain's operations director estimated dishwashing labor was costing the chain ~$15,000/month across all stores, with no consistency benchmark.

Why They Chose JD-3

• 600×400 compatibility. The chain had standardized on Convotherm ovens 2 years earlier. Any dishwasher choice had to fit the tray standard.
• Per-unit pricing. At $4,400 × 12 units = $33,600, the chain investment was achievable in a single capex cycle. Hobart equivalent would have been $84,000+.
• Standardization across stores. One SKU, one training video, one parts catalog. Operations director could enforce SOP.
• Lead time alignment. They needed all 12 units to deploy in a 6-week window. We delivered within the window.

Implementation

The chain ordered 12 JD-3 units in March 2024 with auto-detergent dispenser package. We staged shipping to deliver 4 units per week over 3 weeks, allowing the operations director to roll out installation gradually. Each store deployment took one weekend: install Saturday, train Sunday, live Monday.

Cross-store training was delivered via Zoom in Korean by the chain's head baker, with our team on standby for technical questions.

Results (6 months post-deployment)

• $10,000/month labor savings per store = $120,000/year annualized chain-wide
• Brand consistency restored: all 12 stores now produce visibly clean trays and pastry displays
• Health inspection pass rate: 100% across all 12 stores in the first audit cycle post-deployment
• Water consumption: 38% reduction chain-wide (measured)
• Staff retention: dishwashing-position turnover dropped by 60%, freeing the ops director from constant rehiring

Total payback period: 4.5 months chain-wide.

In the Operations Director's Words

Before the JD-3, every store was its own dishwashing experiment. Now they're all the same. Our brand finally looks consistent in the back-of-house, not just in front.

Continuing Story

The chain has since opened 3 more locations, all with JD-3 units pre-ordered before lease signing. They've moved JD-3 onto their standard new-store-opening checklist.
