Dionisos is Barcelona's tastiest Greek food. With various restaurants throughout the city, it has made a name for itself for providing quality Greek dishes in both a rustic and elegant setting. Depending on the location you frequent will determine whether you're dining at more of a street food location or a sit down restaurant. Dionisos in George Orwell Plaza is your best street food option as there is nowhere to sit inside the small little shop. Their Shawarma and greek salads are delicious as is their hummus and fresh pita. Their Gyros are also amazing, be sure to ask for a lot though as they sometimes give small portions.
