I had to update on this restaurant. Its totally new and different since the new ownership took over in summer, 2011. I've become a fan, and brought or referenced people to it who absolutely love it and have returned. Here's why:
The restaurant features Italian food with sauces and pizza's that are definitely NY/NJ style. That is something you can rarely find in the DC area. Its tasty. One reviewer above referenced the marinara has slightly sweet. I'd agree....the sauces from the NY region when made thickish have a bit of that flavor..but are also rich with spices from vegetables garlic, etc. They are superb,
Pizzas are hand made. You will see Joe, the owner making pizza the classic way, spinning the dough to create a well made crust. You "feel" your way through that. Pizzas are excellent and they come in a lot of variety.
If your local its an absolutely can't beat alternative for excellent pizza and pastas...and frankly I've been everywhere in the immediate area around Arlington. These guys are the best!!!!
Above all else the owner and the staff are extremely friendly. Really outgoing and responsive. Customers come in....and a lot return. Its a combination of flavors, value/price, and the very comfortable, familiar friendliness of the staff.
Finally a little trick value...for happy hour they make some great cocktails with upscale liquors at ridiculously low prices. Killer value. Try virtually anything that gets "sour mix" at typical bars. Toscana's staff substitutes a mixture of fresh squeezed lemon or lime and simple syrup. It improves the flavor only about 1 million percent...and with those happy hour prices you might not find a better drink anywhere for the value.
Oh my oh my. you got my palate excited!!!!
