Most of the Indians in Acton are from South of India, which means they cook extremely spicy foods, lots and lots of oils and lots of red chilles, with simple and inexpensive ingredients such as potatoes, lentils and rice, pressure cooked for speed and convenience. Monsoon specializes in North Indian cuisine, influenced by the Moghul dynasty; lots of ingredients, meats/fish/chicken, cream, butter, herbs, onions, tomatoes, tandoori oven cooking etc...is a lot more labor intensive and much more complicated. Most of it can't be cooked in a pressure cooker, has to be slow simmered, or saute-ed for 20-120 minutes. This is why Monsoon isn't as popular here as it would be in say, NY or Toronto.
The food is very authentic Punjabi/Mughlai, it is prepared to your tolerance level, always fresh, never (in my experience) with stale or questionable ingredients. The service is par with many a rural restaurant. You get seated when the staff figures out you're waiting, and they are almost always understaffed with waiters. The kitchen however, is very well staffed with fabulously talented chefs from the North Indian region of Punjab.
If you can be chill about the lack of "restauranteur" etiquette and just want to enjoy fantastic, authentic North Indian cuisine in an unhurried fashion, then this is the place for you. If you're one of ilk that likes well regimented businesses-like restaurants, then don't aggravate yourself at Monsoon, order take out instead. It is entirely family owned and run by hardworking people who aren't afraid of spending 17 hours, 7 days a week at their jobs. Something I admire!
I've been eating there 5-6 times a year for about six years now, they've catered two celebrations in my home. Everyone has loved their food. I've never had reason to complain. I rarely sit in, prefer take out! I will continue to support this non-chain, family run restaurant...
