More like 3.5. I'm not crazy about the food here, but I love the location, the service and the feel of the place.
They have white table linens and dim lighting and nice tableware, but it's more cozy than fancy. On a snowy night, this was a great place to meet for dinner. You can also check local ads for coupons.
I think maybe I found this style of Thai too rich - but both atmosphere and food are much nicer than Bangkok Balcony on Forbes. As far as Pittsburgh goes, this Thai is second only to Liberty Ave. And I love the squash curry, but then I love anyone's squash curry.
We mostly ate from the Thai menu, but they have a Filipino menu too. BYOB. This is actually the second Sweet Basil, the original is in the Lawrenceville neighborhood of Pittsburgh; that's the one with the outdoor patio.
