Nanny Bill’s, in residence @ Vinegar Yard, London Bridge

Glorious, innovative double patty smash

Burger source
Nanny Bill’s was named in homage to the founders’ grandma, Bill, who ran a cafe in the 70s and 80s. Founded in 2015 in East London as a food truck venture, Bill’s is part of the decade-and-a-half love affair with high quality American fast food Britain is experiencing. Had I known they were famed for their ‘Mac & Cheese’ croquettes, we might have tried those too…

The burgers are interesting; hand pressed, clearly high quality meat, and some interesting variations – from the Dalston Dip (served with gravy) through standard bacon double cheeseburger (with BBQ sauce) through to the spicy Jam burger, various chicken and vegan options and more.

The experience was definitely one for our Covid times. We had to book and pre-order drinks in advance, we had to show our Covid check-in on the NHS app to be allowed in, everything was table service, managed and paid for on our phones, after going to a website by scanning a QR code at the table. It was, per the law, masks on at all times when not at the table. We’d primarily chosen to meet at Vinegar Yard as it provided an outdoor (under cover) space, which felt sensible in the age of Corona. And knowing Nanny Bill’s was there gave us something else to look forward to… their Insta pictures are glorious.

The order
I was tempted by the standard bacon double cheeseburger, but the Jam was calling out to me. Double beef patty, smoked bacon, American cheese, pink onions, hot sauce, shredded lettuce, bacon jam, burger sauce on a brioche bun.

In our rule-of-six compliant group, friends tried the Dalston Dip, the Bacon Double Cheese Burger and the Hot Mess chicken burger. All looked great.

Sidewise, I went for the Aggy Fries – rosemary salt fries, garlic buttermilk mayo, hot sauce, grated Parmesan and spring onion, and nabbed a chicken strip with rum’n’ting BBQ sauce.

The meat of it
So, how was it?

Let’s take a look.

There’s a lot to take in. The crust on the meat is immediately apparent, peeking out from the shiny, super-soft brioche. The cheese has a perfect melt, the lettuce is bright and fresh, you can see the burger sauce forming a protective layer on the perfectly toasted bottom bun.

This burger is a thing of beauty and power. But how did it taste?

In a word? Glorious. The crust is amazingly seasoned and tasty and gives way with a crisp crunch, revealing (amazingly) an ever-so-slightly pink centre. The bun is soft and sturdy (strong and stable?) – it holds up to the fillings and provides a starchy, only-slightly-sweet counterbalance to the umami bomb of the burger and its fillings.

The sweet / savoury / sour contrast is a delight; the melty cheese, chewy bacon, perfectly seasoned meat deliver a savoury mouthful; balanced perfectly with the sweetness of the bacon jam and the burger sauce. The pickled red onions lend a bright sour tang. In the background of the mouthful you can pick up the faintest heat from the hot sauce – a little more would not have been a bad thing.

Every mouthful brought another crunch/chew/taste sensation. It is probably the best patty smash burger I have had in the UK, bar none. Outstanding.

To the sides…

The aggy fries were interesting. A thick coating of hot sauce – Frank’s? – made the centre of the pile somewhat soggy, but amazingly flavoursome; lovely mild buffalo heat with every mouthful. The rosemary seasoning is mild and pleasant, the mayo a lovely creamy contrast to the crisp fries; even the Parmesan plays an unexpected role, boosting the flavour and adding a mild cheesey funk. And of course, I’m one of those people who things chopped spring onions improves almost everything – really wonderful, very moreish, and an extremely creative take on fries, one that adds rather than distracts with its novelty. Obviously the standard rosemary fries are excellent too, and don’t suffer from the soggy hot sauce centre.

The chicken strips were… disappointing .The breading is too light, and underseasoned – insipid. The ‘rum n ting’ BBQ sauce is pleasant, but would have been better cutting through the heat and seasoning of a crisper coating for the wings; as it was, it was not-quite-managing to redeem the juicy, but otherwise flavourless, chicken strips.

Drink wise, we had a very pleasant, fruity and slightly flowery session IPA from the London Beer Factory called Hazey Daze. Can recommend, not least for the outrageous ringpulls.

In all, this was an extraordinarily creative and tasty take on some standard burger fare; the team at Nanny Bill’s clearly know what’s going on and I wish them every success.

Monkey finger rating
Bun – 5/5
Build – 5/5
Burger – 5/5
Taste – 4.5/5
Sides – 4.5/5 –
small penalty for mediocre wings, but fries were great
Value – 4/5 –
£17 for burger and side, ish, with service. OK but not exactly a meal deal.

Burger rating – 4.5/5 – really outstanding overall. Would be tempted to have again, but having seen how amazing their other burgers looked… I’d be tempted to try one of those.

The deets
Nanny Bill’s have a few locations, but if you’re looking for outdoor eating in this time of Covid, Vinegar Yard behind London Bridge Station is the place for you. You can find other locations here, as well as buy their home-kits if you want to give it a try in the comfort of your home kitchen!
