I am a regular visitor to this place. The reason I keep going back is because the place is simply awesome. The ambiance is the coolest, with dim lighting and some awesome tracks playing in the background this place is the sheer definition of happening.
The best thing is that they have a smoking zone which is outside unlike other places where people sit and smoke on your faces which is rather irritating. They have a lavish menu and I can vouch for every item on it that it will be delicious.
Alpha is without doubt the best place to hangout in Chandigarh.
