This was maybe my third week in a row trying to track down the Frenchie after not finding it on Brick Lane a couple of Sundays in a row. This time I was taking no chances and went up to Broadway market. It was incredibly blustery and freezing while I waited for my duck to be cooked until it was slightly caramelised, and the smoked cheddar I had ordered started oozing on the grill. Other cheese choices are blue cheese or goat's cheese with truffle honey. Next time I might try the goat's cheese. I think the tang would work well with the sweet chutney and sweet brioche.
The only downside I would say is that for £6 it's a little small so not incredibly filling - especially compared to the monster buns I'd had the night before for only £7. But I have noticed that the price of street food has been creeping up lately, and £6 isn't an unreasonable amount to charge compared to other vendors. It certainly wouldn't keep me away.
