At Sion, this is probably the only bar and restaurant which is an excellent family restaurant and also provides great value for money. Peninsula is bloody expensive and you get the same quality of excellent food at Yogi.
Even during peak season, you manage to get a seat at Yogi, possibly because of the location which provides less parking space if you are in cars, but they have valet parking. It is a nice place for a quiet evening with family and friends. Per person expense would be around Rs. 150 if you dont drink or Rs. 250/- with drinks.
The ambience is just right, not too showy and not too bad either. Their other restaurant at Chembur diamond Garden is also very good. Try the kebabs at this place. They are quite good. The servers give you personalised treatment and are very friendly.
