If you travel between Mumbai and Pune, and visit hotels/restaurants in both the cities, then I'd strongly suggest visiting Paasha before visiting Dome or Aer in Mumbai. You'd appreciate Paasha more that way. Unfortunately, I visited Paasha after I had my breath taken away by Aer, and hence it underwhelmed.
I had snuck up to Paasha one of the times I was at Spice Kitchen (Marriott restaurant) and I was awed by the look and feel of the place. I had a very brief look and swore I'd be back, and so I was back with family for weekend night drinks. Was also around my mother's bday.
One enters the Paasha terrace space through a cavernous covered room, which serves as the mains serving area. The terrace space is divided into two sections by a long bar. To the left is the brighter part of the terrace because this side faces the city, the brightly lit SB Road, etc. To the right, is the darker/quieter portion, which faces (to my knowledge) the Vetaalbaba Tekdi line. I'd have preferred to sit on the left but they didn't have large sofas to seat 5 so we took the darker side. Wasn't so bad, really.
Generally, we had a great time but I attribute most of that to the company and the discussion. My aunt ordered a glass of wine on recommendation and she said it was very ordinary, and moved to a safer beer. My uncle took a Belgian beer, I stuck to my regular desi beer, and my Dad decided to get Chivas. My Mom either had a daiquiri or a mojito. I forget.
The finger food was reasonable as were the appetizers. Nothing exceptional.
They do have this thing that they only serve appetizers on the terrace side. You'd need to move indoors if you want mains. Strange.
The ambiance and the view -- A beer's a beer and a single malt is a single malt. One visits Paasha (or Aer or Dome) for the view, the ambience, and the breeze. I'd say visit once just before sundown. You'd probably enjoy the place more.
We entered the place past 9 and the view of the city side underwhelmed. For one, Pune is not a very brightly lit city, and it is very well-covered with trees, which makes 'the view' kinda comme ci comme ca post-dark. I'd assume it would look stellar on a rainy evening or when there's still some sunlight remaining.
Breezy it is, and I quite liked the white tone leather furniture (one sees that at Dome in Mumbai). Surprisingly, it was very sparsely populated, which makes for bit of a downer.
I don't even remember what the service was like, which is a bad thing. Other than the Tatas and Bhosales, the regular guy visits 5 star places infrequently, spends (what he considers) a bomb, and expects special service that he would remember for a long time. Not the case here.
Overall, a reasonable time was had. Total damages (food + drinks + taxes + tip) -- 10k. Not cheap, but then I live in Mumbai and by Mumbai metrics the pricing seems acceptable.
