While North End Regina still holds the top spot, T. Anthony's pizza on Commonwealth now enters our favorites short list for what we consider "regular" pizza (thinish, crispy/chewy crust with lots of flavor, tomato-rich sauce, good ratio of cheese, and fresh toppings -- sausage and garlic in this case).
We ordered a whole small pie --service was quick and the price was right ($7 and change). We'll definitely be back! They also offer slices as well which really need to be tried to really judge this type of place holistically.
For a reference point, other favorites in this category include Santarpio and Il Panino on Mass Ave in Cambridge, and sometimes Sabatini's in Arlington.
Our "regular" category doesn't include Emma's, Za, or Figs, by the way (all of which we like, but it's not really pizza, is it...)
We also hope to try The Paddock in Somerville and New Town Grill in Porter Square Cambridge based on postings here...
