I stay nearby to chowpatty so have been to sukh sagar restaurant several times.The ambience is good.The staff over there is also good.
The food over there is awesome, specially pav bhaaji.Its a vegetarian restaurant, You get various other dishes as well like chole puri, naachos, Food quantity is really good over there.I have been over there mostly during the weekdays If you go during the weekends there is lot of wait time of around 20 to 30mins, Overall its a very good family restaurant to hangout with, Its slight on the expensive side, But its a value for your money
