I had the lava cake with ice cream today. The service was friendly and quick, but the dessert itself was very unimpressive - I've had this before at a Toronto location, and it was very good (my only complaint was that the lava cake is on top of the ice cream, which makes it a bit awkward to eat). Over here though, the "lava" cake didn't really have the oozing lava fudge like it's supposed to... instead, it was basically a slightly warmed brownie with chocolate sauce.
Not bad for that, but then it certainly shouldn't be called a lava cake.
