Roys pizza will deliver but are expensive for a small pizza.

In LC can't really think of a decent pizzeria, theres a brilliant one near me in Los Abrigos, but not near you. Actually Bella Roma, a restaurant on the corner of Port Royale do very good pizzas

In Las Americas, the Tuscany is my favourite pizza place, the best one in my opinion is the one near Jazzisimo opposite Starcos.

Good luck!!

The Bella Roma on Port Royale do take aways ( no delivery service) reasonable price and good pizza.

There is als a new Pizzaria on El Mirador but havent tried it YET

"Pizza May" do brilliant pizzas, they are up the road (hill) from Tenerife Sur apartments, and they also deliver, there is also a new italian in one of the locals in El Mirador, but have not eaten there myself yet.

Can recommend the pizzas at Bella Roma grill also but it depends whereabouts you are staying in LC, its a long walk up that hill.
Reminds me of when I asked my husband bring back a take away pizza from there while I got a salad ready - when he got back he had the box tucked under his arm like he was carrying a newspaper

The Italian under El Mirador is supposed to be very good, I've not been but my mate recommended it to me
