I really liked some things about Famoso, while other things weren't to my liking.
The prices at Famoso are better than some of their competitors (up to $4-$5 cheaper for comparable types/toppings). I personally prefer a very crisp pizza crust, but Famoso seems to be going more for the flexibility of the "fold your slice in half" to eat kind of crust. Some people may prefer this type of pizza. I found that the toppings were plentiful, but that some (such as the tomato based sauce) were overly bland.
The service system was a little awkward. I understood that you order at the till, which was totally fine, but there were also a plethora of servers (4+ different ones during our meal) who came by to see if we wanted more drinks or food. Perhaps they are trying to provide great service, which I appreciate - but I kind of wish they'd choose a system and stick to it. If there's going to be waiter service, one waiter would be better so that there's some continuity rather than random staff stopping at the table at random times.
Famoso is a decent pizza joint, but I'm not sure that I'll be back, given so many other options in the downtown area.
