I tried the Five Guys in London last night, and while the burger wasn’t bad at all (I still prefer Honest Burger 😉 ) it was lucky I checked online first to see if they contained any lactose.
You’ll see on their site https://www.fiveguys.co.uk/faq#q1 that their buns contain dairy. While this isn’t bad in itself – the fact that this is on the site and I couldn’t find it in store or any warning on the menus in the store is frustrating!
I was actually given the wrong burger first, with a lettuce bun (did the secretly know I’m lactose intolerant?)- which is a nice option for anyone who still wants to eat at Five Guys, but there needs to be clearer labeling in store that their buns contain dairy as its not a given, that a standard burger bun will contain dairy. Even if it was labelled as brioche it would be clearer.
