The 12-outlet burger chain with a delivery brand ahead.
Flame Stack Burger. Twelve outlets across three emirates. Revenue flat, four underperforming. The founder wants a delivery-only fried chicken brand running from existing kitchens.
The question.
Flame Stack operates twelve dine-in burger outlets across Dubai (eight), Sharjah (two), and Abu Dhabi (two). The founder wants to launch a delivery-only virtual brand (a fried chicken concept) and is weighing two paths: run it as an overlay from the existing outlet kitchens during off-peak hours, or rent stations in shared kitchen facilities (typically AED 50,000 to 100,000 setup cost per station).
The overlay path sounds cheaper, but the founder does not know which kitchens can handle the additional load, or whether the compliance and infrastructure cost of retrofitting them would push the total above the shared kitchen alternative.
The engagement.
Ten weeks structured in four phases.
- Weeks 1 to 2. Portfolio audit across all twelve outlets. Kitchen layout, equipment utilisation at peak hours, electrical and gas capacity headroom, exhaust system load, refrigeration condition, compliance status.
- Weeks 3 to 5. Outlet-by-outlet viability assessment. Map each kitchen's spare capacity during off-peak hours. Identify which outlets are structurally unprofitable (rent-to-revenue ratio after 15 to 20% rent surges in 2024) versus operationally fixable.
- Weeks 6 to 8. Virtual brand kitchen overlay spec. Additional equipment needed: fryers, holding stations, dedicated dispatch area for delivery riders. Can the existing hood systems and electrical supply handle the added frying load? Where does the ingredient overlap allow shared cold storage, and where does it create cross-contamination risk between raw chicken and burger prep?
- Weeks 9 to 10. Final report with recommendations and a phased rollout plan.
What we found.
Two outlets had energy costs running 40% above the portfolio average. Mid-sized QSR kitchen benchmark: approximately AED 8,000 per month electricity (DEWA commercial rate, 38 fils/kWh). These two were closer to AED 11,000 per month due to ageing refrigeration compressors and undersized exhaust forcing HVAC to compensate for kitchen heat leakage.
Three outlets had compliance gaps: grease trap sizing below Dubai Municipality Food Code 2.0 requirements, and one outlet's fire suppression certification had lapsed. Annual Civil Defence certification is mandatory for all gas kitchens (AED 15,000 to 50,000 depending on system size).
Staff turnover across the portfolio was running at roughly 40%, consistent with the UAE industry benchmark of 43% annual BOH turnover. Each departure was costing the operator AED 8,000 to 12,000 in recruitment, visa processing, and retraining.
The fried chicken concept would need two additional double-basket fryers per outlet (AED 18,000 to 24,000 per pair) plus a dedicated dispatch station for delivery packaging. Seven of twelve outlets had enough electrical headroom. The remaining five would need panel upgrades.
Delivery commission exposure was significant: platforms charge 25 to 35% per order. At a blended AED 45 ticket, commissions would consume AED 11 to 16 per order. The model only works if the virtual brand clears 40 or more orders per day per outlet, and the own-channel share reaches at least 15%.
Cold storage separation was a genuine constraint. Raw chicken and burger patties require separate refrigeration or at minimum physically separated shelving with dedicated containers to meet Food Code 2.0 cross-contamination requirements. Four outlets had no spare refrigeration capacity at all.
The trade-off.
Overlay path. AED 35,000 to 50,000 per outlet for equipment and modifications, but only seven of twelve outlets have the electrical headroom. The five that do not would need panel upgrades (AED 15,000 to 25,000 each), pushing their overlay cost to AED 50,000 to 75,000 per outlet. Four outlets have no spare refrigeration capacity and would need a dedicated reach-in (AED 8,000 to 12,000).
Shared kitchen path. AED 50,000 to 100,000 setup per station, no infrastructure risk, no compliance liability, purpose-built for delivery dispatch. But the operator loses the off-peak labour leverage: existing BOH staff could run the second brand during slow hours instead of hiring a separate crew.
Recommendations.
- Close two structurally unprofitable outlets.
- Pilot the virtual brand as an overlay in two outlets with the most spare capacity, electrical headroom, and adequate refrigeration. Off-peak hours only. Two additional fryers, a partitioned dispatch zone, a dedicated reach-in for raw chicken. Estimated overlay cost for two outlets: AED 70,000 to 100,000 combined.
- Do not overlay the remaining outlets. For the five needing panel upgrades and the four with no spare refrigeration, the per-outlet cost approaches or exceeds the shared kitchen alternative, without the purpose-built dispatch infrastructure. If the pilot succeeds, expand via one or two shared kitchen stations.
- Do not roll out beyond the pilot until the brand clears 40 orders per day consistently for 60 days. Below that threshold, delivery commissions make the overlay unprofitable.
- Retrofit grease traps in the three non-compliant outlets and renew the lapsed fire suppression certification. This is a portfolio hygiene issue independent of the delivery brand.
Two outlets closed. Delivery brand piloted from two existing kitchens at AED 70,000 to 100,000 combined overlay cost. Expansion path redirected to shared kitchen stations for the outlets where retrofit costs exceeded the shared kitchen alternative. Compliance gaps addressed across the portfolio.
