There's no place like home, and you'll feel like you're back there from the moment you squeeze into a table at this hole in the wall just across the river from Castel Sant'Angelo. There's no menu, just plate after plate of whatever Ada thinks you should try, from hearty, classic pastas to involtini di vitello (savory veal rolls with tomato) and homemade sausage. Sit back, relax, and enjoy -- it's all good. By the time you leave you may have made some new friends, too.
