Rodas
Rodas is actually 3 eating establishments in one. A fashionable restobar, oriental restaurant, and all night coffee shop.
Parabola - the coffee shop has decent, cheap midnight buffets (199 on weekdays). It usually has lunch and dinner buffets at 275-375 depending on the day. The buffet is quite ok. There is no Midnight buffet on Monday nights. Some Indian and Continental main courses, and coffee is available all night.
Far East - this is a very good oriental restaurant on the first floor. They offer Thai, Chinese, Japanese, and Vietnamese starters and main courses. Most are quite good. Price is steep as expected, but food is usually very good. A standing pomfret curry of theirs is a favourite.
Aura - this is the fashionable resto-bar. It usually holds Swiss/Italian/other International food festivals. Haven't particularly like any. The price/satisfaction ratio is skewed. Otherwise, Aura is a very good bar with live music, fashion shows, and occasional pole dancing.
K-5 Lounge
K-5 lounge is a different experience, simple elegant interiors, good music, a lcd screen, limited seating and ample free space, very comfy low seating, not at all congested. specialities thai food, cocktails, service excellent very homely staff.
Location is a bit odd, located in koregaon park lane A ,the lane behind german bakery, but once you are in the lounge its a world apart, i think the only lounge to be open all day long, the even have happy hours during the day. The ambience is such that whatever time you go you will feel its just night.
Worth the money
