This is one my favorite places in Paris for a lovely and fresh dinner: L’Alcazar .
Situated in the 6è, near St Germain des Près, it is in a quite street that the art deco restaurant takes place.
The high ceiling, big glass roof and green plants create a great peaceful atmosphere. Light and trees will definitely make you feel at ease.
Apart from the beautiful environment, the menu is diversified and the service is very nice.
It offers great choices of fish, which I recommend, of course, menu depends on the season. Have a look to their website for more information.
There are also lovely private dining rooms if you wish to book the area for a special occasion. And a bar, Le Balcon, which I didn’t have the chance to discover yet. Although, it offers live music, djs and others styles, time to time.
