We were thrilled when a stack'd opened right nearby: we are regulars at the one in Oakland in Pittsburgh. That one is excellent.
The restaurant is nice and everything is perfectly ok. However, on the several occasions we've been here, the food was always "ok", as opposed to delicious and perfectly spot-hitting in Oakland.
If that were it it would be fine, but the prices for everything - the exact same items - are just higher at the Wexford restaurant.
Just go to Oakland.
