I did eat at Hot Home Pizza in June 2013. The pizza was amazing, I did eat pizza number 3 on their menu. It's absolutely recommended. The waitress was very service minded and when one of my kids could not eat what's was on the menu due to allergy, they made a new dish for my kid that was very good.
What was not that great is that your getting interrupted by guys selling stuff several times during the meal. Pirate copy's of bags music etc... The seating area outside is very open in the middle of the street, people did not mind walking between the tables. In Spain lots of people smoke and for some reason they like standing very close to people that is eating. Personally I don't enjoy people standing around me smoking when I am eating, and I get angry when people walk up to me and want to sell me some crap while I'm eating. That's why I can't give top score in atmosphere.
