I've been looking for a great hot chocolate place in Toronto for awhile now and I think I've finally found it. They serve a thick, rich sipping chocolate or a thinner version with steamed milk. Both are excellent and make Xococava the best spot for hot chocolate in the city in my opinion.
As well as hot chocolate Xococava also has a variety of truffles, sorbet, and various other desserts on offer. They seem to be known for having adventurous combinations of flavours in their truffles. I tried a chai flavoured truffle ($2), one of the more tame options, and it was delicious. The center of the truffle had a great, gooey texture and the chai flavour was just right - not too overpowering. I also recommend the little churros ($0.50), they're great on their own and even better if dipped in your hot chocolate. The sorbet is not the best I've had but it is excellent and they have some interesting flavours. The plum was quite good as was the lemon, which tasted like lemon curd and not typical lemon flavoured gelato.
The two girls behind the counter were very friendly, helpful, and fun. The place is a little hard to find and there's only enough seating for about four people inside and a few more outside if the weather's warm.
