To the best of my knowledge, Sanaa shares an identical bar "menu with pictures" with other Disney establishments, however, they use a different menu cover. One thing that we found unique to Sanaa was their Wine menu, which contained wines you would not necessarily see elsewhere. Our server made the wine suggestions since we were unfamiliar with the wines, and they were great choices. We had a truly wonderful meal at Sanaa, seated at the windows, watching the giraffes.
If you mean a separate food menu, no. I know for certain that they serve the appetizers and desserts from the regular Sanaa menu. I'm not sure whether they serve the entrées in the bar as well.
