I'll keep this short. I took a friend to Mio for her birthday. The food was all very good, we had: tostones (fried plantains), arepitas (cheese filled savory fried dough) with black beans and slaw, salmon, and pork tenderloin. And for dessert we had Puerto Rican coffee (delicious!) and guava cheesecake (also delicious!).
The service was amazing and they were even nice enough to take a few pictures for us to commemorate the evening.
Definitely would recommend anyone visit Mio for a simple, elegant, and well-seasoned dining experience!
