I went to Queen Margherita on a Saturday at around 7:30pm with 2 friends. It was super busy, but they offered to accommodate us at a table for 2, or else we would have to wait until approximately 9pm. We agreed that the table for 2 would suit us just fine.
My friends ordered the calamari as a starter, and they said that it was very good - crispy but not too greasy. We each ordered a pizza, I had the Cinque Stagione (a white pizza with veggies), and my friends had the Gio Oldschool and Alla Campagnolo pizzas. I was a little disappointed that none of the rosso pizzas were vegetarian-friendly, but I did very much enjoy my pizza. The crust was thin, the pizza was cooked perfectly, and it had a great flavour - the combination of toppings went together very well.
Our server was super nice and very attentive. She took our orders quickly and came back to check on us during our meal to make sure everything was to our liking.
Ultimately, I would really like to see some vegetarian-friendly red pizza options, but I very much enjoyed my experience and would definitely eat there again.
