Trattoria...hum, I don't think so, tourist trap more like. All we wanted were two pizzas, a seemingly simple request from a "restaurant" professing to be Italian. How wrong can it get? Very it seems. The waitress was a disaster, she got the drinks order wrong (we ordered a coke and a bottle of sparkling mineral water), she could not describe any of the pizza topping (there were only 4 pizzas on the menu) and she literally plonked all of the plates in front of my friend when stacking them up to take them away. But in truth, a lot can be forgiven for good pizza, except that the pizzas were dreadful. Small, oily bases, clearly prepackaged, cheap tomato sauce, and every topping clearly tinned or frozen - absolutely vile. I can't comment on their other more elaborate dishes, but if they can't get their basics right...
Avoid Trattoria Montebianco at all costs.
