I've been to Slice of Vegas 2 or 3 times and have never been disappointed. They have a great vegan menu. I've tried the barbecue "chicken" pizza and the vegan burger with a heap of sweet potato fries, which were all excellent. I finally managed to save room for the vegan chocolate cake (with peanut butter frosting!!!) the last time I went, and it was AMAZING! I want to eat it every day, for every meal, but then someone would have to roll me around like Violet Beauregarde.
Our server on this most recent visit, Brent, was super nice, too. He got a big tip. :)
