FAQs: Keto at Leon
What's the best keto order at Leon?
Build your own plate from SIDES: 2× Chargrilled Chicken Mezze (0.6g each) + Leon Slaw (5.4g) + Kimchi (2.7g) = ~9g total carbs, ~45g protein, ~20g fat. This beats anything on the main menu and costs under £15.
Are Leon's GFC (gluten-free crispy) nuggets keto?
No! This is a common trap. GFC nuggets are gluten-free but still 20-25g carbs because the coating uses rice flour and starches. 'Gluten-free' does NOT mean 'low-carb' at Leon.
Can I order rice boxes or wraps without the rice/wrap?
No - Leon doesn't offer bunless/riceless options. The rice boxes come with brown rice tamari base (45-55g carbs), and wraps use khobez flatbread (46-65g carbs). Order from the SIDES section instead.
What's the best Leon breakfast for keto?
Shakshuka (6.4g carbs) - two poached eggs in paprika tomato sauce with aioli. Perfect keto macros (25g fat, 17g protein) and genuinely delicious. Available until 11am.
Is Leon available nationwide?
No - Leon is primarily London-based with restaurants in a handful of other UK cities and motorway/transport hubs. Check leon.co for your nearest location before planning around it.
