Cons: I detected none. I must preface this review, however, with 3 important factors that shaped my experience:
1) I have eaten at Passage to India only once
2) I ate in the early evening on a weeknight
3) I visited as a vegetarian - so maybe I should leave a second review based on a vegan perspective!
I enjoyed the relaxing ambient lighting and spacious, comfortable booth seating. The waiter acted professional. I found them polite and hands-off (we concentrated mostly on the buffet), which I prefer to hovering waitstaff. As for the food offerings, the omnivore and I found satisfaction with the selection! I adore curry and also like to eat light and low-calorie, whereas my date for the evening likes heavy, meaty foods. The fact that we both enjoyed ourselves suggests its versatility as a dining establishment. Overall, I would recommend dining there and believe that it would work for a date, business meeting, and family gathering place (though I did not pay any attention to whether they had child friendly - I mean, bland and generic - options).
