This place was recommended to me by a friend who had visited before me, AND my airbnb host, so that was already a telling sign.
The main reason we came was for the 2 for 1 margarita deal they have from 1-4 PM, which comes out to about 10 USD/marg. There is a selection of 4-5 different margaritas, and you choose one type to get for both. Choices include the classic marg, spicy (w/mezcal, is not actually spicy at all), cucumber, and a couple of others. They weren't too sweet, and we enjoyed them on the beautiful patio area overlooking the beautiful beach. They have a DJ playing smooth tunes, and the environment is relaxed, casual, and blissful.
We didn't get any food, but the menu (Thai food) looked quite tasty. The owner supposedly grows Thai ingredients locally for their dishes, and had an interesting story of how he came to start the restaurant in Tulum.
Drink 2 margs (or more), watch the waves, get hungry, eat Thai food, and then transform into a beached whale on the white sands of Tulum. Trust me, it's worth it. read more
