Gwen Stefani & Blake Shelton: Scene From An Italian Restaurant

Gwen Stefani still has Blake Shelton head over heels for her 8 months into their relationship if what he's drinking is any indication.

Blake took Gwen on a romantic dinner date Thursday night at Trattoria Dell’Arte in Midtown Manhattan.

We're told they ordered a 2011 bottle of Silver Oak Cabernet, which goes for $140 with dinner. No biggie, except Blake's usually a whiskey guy ... so he's still smitten, for sure.

As for food, he got veal chop parmigiana and she got the dover sole. We're told very few people noticed them until they got up to leave their corner table.
