FAQs: Keto at GBK (Gourmet Burger Kitchen)
What does 'GO NAKED' mean at GBK?
It's GBK's official branding for bunless burgers. Just say 'GO NAKED' and the kitchen knows exactly what to do - they remove the bun (~35-40g carbs) and replace it with GBK Homeslaw + Simple Green Salad. No awkward explaining needed!
Is the Homeslaw zero carbs?
No - this is important! Homeslaw is ~9-14g carbs because it contains pomegranate seeds (a genuine sugar source). It's manageable and included in all our GO NAKED carb estimates (~10-18g total), but it's not a free-carb item.
What's the best keto burger at GBK?
Classic Double GO NAKED with cheddar, bacon, jalapeños, and house mayo (NOT relish) = ~10-13g carbs, 76g protein. That's 12oz of British grass-fed, dry-aged beef - one of the highest-protein single meals on FastKeto.
Which sauces should I avoid?
SKIP: GBK relish (~8g), habanero jam (~10g), BBQ sauce (~8g), onion jam (~8g) - all sugar-based. CHOOSE: House mayo (~1g), chipotle mayo (~3g), garlic mayo (~2g), blue cheese mayo (~2g) - all fat-based and low-carb.
What makes GBK beef different?
100% British grass-fed beef, hand-selected chuck/brisket/short rib cuts, 30-day dry-aged steak. This is genuinely premium quality - not frozen patties like most chains. GBK is UK-founded (2001) and mid-market pricing (£10-13 per burger).
