What a disappointing experience I had at Magpie a few weeks ago... ordered the mortadella pizza (which at $25 is already expensive enough on its own) with a gluten-free crust (the most expensive GF extra I've ever seen). I received a pizza with a couple paper-thin slices of mortadella and barely any visible cheese on it. At that price, I would've expected far more toppings.
The GF crust was good, very decent texture, although a bit sweet for my taste - but definitely not amazing enough to justify a $7 extra! I was really looking forward to being able to eat at such a hyped-up place, but at that price I did not find it worth it.
