Bars:
IOA:
Backwater Bar: It's in the Port of Entry adjacent to Confisco's. It is a small full service bar with some nice themeing.
Hog's Head Pub: In the Wizarding World of Harry Potter. A good selection of British beers.
USF:
Finnegan's: Great food and atmosphere. Feels like a real downtown establishment.
Restaurants:
IOA:
Mythos has some of the best themeing of any theme park restaurant ever. And also very good reasonably priced food.
Confisco's is also very good and reasonably priced with themeing elements from all the lands around IOA.
USF:
Fennigan's also while being my favorite drinking establishment in all of UOR also has some darned fine food.
Lombard's is also a nice well themed seafood table service.
Universal Orlando Resort Signature Dining (All very nice):
Emeril's Orlando in CityWalk
Emeril's Tchoup Chop in the Royal Pacific
The Palm in the Hard Rock Hotel
BiCE in the Portofino Bay Resort.
Special Mention goes to The Thirsty Fish at the Portofino Bay Resort. It is a great place to have a Cheese Board and a bottle of wine. It has inside and outside tables that overlook the harbor. One of the most relaxing places in the entire resort to chill. In the pic below, BiCE is upstairs and the Thirsty Fish Bar is downstairs:
