In-Between Meals on the Norwegian Sun
Sushi and Sashimi Bar on Norwegian Sun:
The Norwegian Sun offers a nice selection of sushi. According to guest reviews, the consensus is that the quality of the sushi is better than what you would find in a grocery store (but not by much). This is also a great place for sake! All drinks are at current menu prices, and there's a 15USD per person charge (there have been reports that a la carte pricing is also offered). This bar is located on Deck 12.
Las Ramblas Tapas Bar onboard the Norwegian Sun:
Norwegian Sun's Las Ramblas Tapas Bar features a fine assortment of Tex Mex and Southwestern appetizers. This restaurant lounge is located aft on Deck 12. Typically, there's a 10USD per person charge for guests for Norwegian Cruise Line's Tapas restaurants. Check when aboard for hours
