Naturhotel aufatmen in Leutasch calls itself a vegan hotel in Tirol and serves a vegan four-course dinner made with regional produce. The site says ten seats a day are kept for guests from outside the hotel by phone reservation, from 18:30 with orders by 20:00 and closed on Wednesdays and Sundays, and it does not mention gluten free cooking. Tell the staff about your allergies, the kitchen has the final word.
