Patio San Eloy
Cerveceria 100 Montaditos
And for dessert...
You cannot leave Seville without taste famous churros con chocolate, which is usually a brekfast snack but it is also nice to have them during the daytime. To eat the best churros we reccomend Chocolateria Virgen de Lujan 41 or there is also a very nice stall on the corner of C/Arjona and Puente de Triana(Isabel ll)
