I love Horizons! I've eaten here twice and been fully satisfied both times! The first time we tried the chefs tasting menu, which was great. The parsnip soup was one of the best things I've ever tasted. Our broiled tofu was perfectly crispy on the outside and silky smooth inside. And the sticky toffee pudding was to die for. I've also had the seitan entree, which was very good. My favorite desserts are the Irish Cheesecake (a St. Patrick's day special I think) and the toffee pudding. I found the chocolate mousse cake a bit too dense, the beignets rather heavy, and the creme brulee too tofu-y. But my friends all had different opinions, so try them all! I also was not impressed by the truffle fries; they were bland.
All in all, this is my favorite restaurant! Furthermore, because there's not meat on the menu, it's much cheaper than your average gourmet restaurant. Woo! And also, service is great.
Cons: A few weaker dishes
