Big Kahuna is a chain of lounge bars which currently is in Lower Parel and Phoenix Kurla. Being new they have incentives such as very generous happy hours to draw you in. Grills are at the core of the menu which also features burgers and noodles. The outlets have a nice buzz in the evenings, specially on weekends. The music can get a bit loud though. Afternoons are pretty empty though and makes more sense to go there to grab a bite. Service can occasionally be a bit slow.
