Looking for restaurant recommendations (Rome)

Hi All,

I'm looking for recommendations for inexpensive / reasonably priced restaurants in the city serving the following cuisines:
(p.s Not so fussy on the ambience but more on the authenticity of the menu).

Thai restaurant?

A good lebanese restaurant?

Turkish restaurant? And last but not least...

A good Indian restaurant?

Good places for weekend brunches? Anyone had a reasonable champagne brunch out there?

Thanks in advance!
