...per the Saber class write up at ACTD Starship Design Bureau:
This is a small lounge located on deck 5 and is set in the forward edge of the primary hull. It has a very relaxed and congenial air about it; The Observation Lounge is the only place on the ship where rank means nothing - "sir" need not be uttered when a person of lower rank addresses an officer, and everyone is on an equal footing. Opinions can be voiced in complete safety. This lounge is the social center of the ship.
The Observation Lounge has a small number of recreational games and assorted "stuff". 3-D chess and other games can all be found here. There is also a bar (self-service) which is stocked (at the Captain's discretion) with various potent alcoholic beverages, such as chech'tluth, Aldebaran whiskey, Saurian brandy, Tzartak aperitif, Tamarian Frost, C&E Warp Lager, Warnog, Antarean brandy, and many others as well as a small food/drink replicator that can make the synthahol versions of these and other drinks.
The Observation Lounge is often named by the crew, and is decorated as the crew decides and usually has a theme, to some extent. A small number of tables and chairs, as well as some benches, provide seating for the crew. Large windows set into the forward wall allow a breathtaking view from the bow of the ship, giving a clear view of what lies before the ship. Situated under the forward torpedo tubes, they also allow for a 'you-are-there' view of the launching of these destructive devices.
I know... it doesn't necessarily say anything about "food" but, I imagine that it's a much nicer place to have dinner than the Enlisted and/or Officers' mess halls... The view is certainly better, anyway.
