Small Private Room

It seems like there might be a bit of confusion in your question. In the US, there is no specific food named "small private room" that is commonly found in restaurants. However, there are certain types of dining experiences that might take place in a private room within a restaurant. These can include:

1. Private dining rooms: Some restaurants offer private dining rooms that can be reserved for special events or large group gatherings. These rooms are often separated from the main dining area and can accommodate anywhere from 10 to 100 guests.

2. Teppanyaki or hibachi tables: These are types of Japanese cuisine where the food is cooked on a flat griddle in front of the guests. The griddle is typically located in the center of a large table that can seat up to 10 people.

3. Korean barbecue: Similar to teppanyaki or hibachi, Korean barbecue involves cooking meat and vegetables on a grill at the table. The grill is usually built into the center of a table that can seat 4-6 people.

4. Sushi bars: Some restaurants have a dedicated sushi bar where chefs prepare and serve sushi and sashimi. These bars are often located at the front of the restaurant and can seat up to 10 people.

Overall, while there is no specific "small private room" food in the US, there are many types of dining experiences that can take place in a private setting within a restaurant.
