La Brasserie Street food cart’s lone, titillating entrée item has sold out regularly since opening April 11.

To date, its ‘fresh out’ record time is 1 p.m. — a mere two hours after beginning lunch service.

Causing the kerfuffle is a gravy-laden, beer brined chicken sandwich, aptly named, Brass Chicken Sandwich ($6.25).

If its crispy fried onions were discarded, I’d run the risk of confusing the warm creation for a delicious, edible mini pillow.

But the skinny, deep-fried onions cannot be omitted. They are softly sweet and addictively crunchy — perhaps a sell-out kind of side dish of their own someday?

The floury buttermilk bun could’ve passed as a Portuguese and the juicy rotisserie chicken — treading in hot gravy — lacked any beer flavour.

Regardless, the assemblage was the kind of thing to warm bellies on drizzly Vancouver spring days.
