If you are a strict vegetarian and is looking for a quick bite in Chowpatty area, Sukh Sagar is the right place, the food is good. Nothing special about it but very pricey compared to other South Indian restaurants. Another advantage is you can get different varieties of food, from south Indian to Chinese. Patronizing SS once is a while is ok. However, a word of caution. Strictly avoid going there on Sunday evenings.
The crowd is maddening, the scenario is as if a famine is going to arrive !
