I've been here a few times. A cheap and delicious meal in Sitges! See my pic: 1/2 rotisserie…read morechicken, fries (chips), draft beer = under 10€, about US10.
Just order at the outside window if you're taking out. Order at the inside counter if you're eating in. The decor is nice and fresh like their chickens. It's a clean, modern fast food restaurant.
The chicken is really moist and tasty. 1/2 chicken sounds like gluttony but it's not. Fries are good. Estrella draft beer yummy.
It can get super crowded with lines out the door. Yesterday they closed for siesta, but many do in Spain. I'm getting used to siestas myself!
