Buyers using the flaming red "Mr. Go Pizza" machine can choose from four different kinds of pizzas costing from 4.50 to 6 euros ($5.20--$7.20). The machine kneads and tops the dough and customers can watch the pizza cook behind a small glass window. Reviews by customers on Thursday of the machine, one of the first in Rome, ranged from "acceptable if you're in a hurry" to outright horror. "It looks good but it is much smaller than in a restaurant and there is less topping," said Claudio Zampiga, a pensioner.
