Yam patty portobello burger

This burger is cute and healthy, though the patty is really soft and more like mashed yam than a solid patty. The fries are fresh but quite soft. My friend who ordered this was full when he'd eaten about two-thirds, so the burger is deceptively filling.

It is creative and original. But I felt that it was missing sauce and taste. The idea of having portobello as buns is original but doesn’t give the taste of crispy buns.
