This place is great. I've been here quite a few times and each time I find another reason to go back. The food is excellent across the board. Panini, the sub, or just the meatballs; It's all a tasty en devour for your mouth.
The pizza on the second floor is fantastic and the drinks on the third are worth spending the time and money. If it wasn't enough, they have a great beer selection on the first floor as well and the service was polite and timely. I highly recommend Sienna Mercato for what it's worth.
