I visited Arlequino's after my boyfriend and I had a pleasant experience at the owners' other establishment, La Medusa.
Though I can't speak for the other pizzas, I absolutely loved the pizza I ordered, which was the San Bennedetto (lobster meat and rose cognac sauce). What especially impressed me, however, was that hot pepper antipasto sauce was readily available on all tables. As a Southern Italian, I am always looking to spice up my food - so this was a welcome bonus rarely seen in most restaurants.
The only negative I can think of: the entire waitstaff has been hired based on their looks and clearly not on skill. So if you're a critical foodie that has lots of q's for your waitress or waiter and looks for exceptional service...this is definitely not the place for you.
If not - then splurge on the San Bennedetto and enjoy!
