This place was great! The owner is friendly and very attentive, and all staff are helpful with veg*n diets. They brought out little tasters of all the drinks on offer, and talked us through the meat-free options.
The Kaxapas are massive, so it might be better to share one between two people at first, then see how you go after that (my partner and I both had trouble finishing ours, and had to take the leftovers with us. They're delicious, though!)
