Basics has some of the best prices on produce in the entire area; they are consistently 30 - 60% cheaper than Pathmark or ShopRite. They do not have much selection or good prices on other items, though. You have to bring your own bags or buy theirs.
The ShopRite in North Bergen is always very clean and usually well stocked. It is located in what has to be the world's worst planned shopping center -- there is only one entrance from local streets, and only on a street going one direction. If you are coming from the opposite direction, you are out of luck and have to make a complicated detour or a dangerous U-turn across 4 lanes of traffic.
The Pathmark store in Weehawken was remodeled about a year ago; the new design is more customer-friendly and they seem to be keeping the store cleaner now, too. They often sell out quickly of sale items and are very slow to restock them.
The selection at Indian Bazaar is ok, but not that great. I would go here only if I needed something quickly and did not have time to travel to another grocery. Their location is very convenient, but their prices are not great.
I have visited Praba Indian Salon only for eyebrow threading (hair removal by using waxed threads), which they do a wonderfully and for a very cheap price. They also do lovely mehndi (henna) work for brides.
Indian Village Jewelers has a nice selection of new and "vintage" (used) jewelery. I did not find their prices to be either better or worse than other shops. Most of their items are not to my taste but sometimes they have lovely pieces.
I have taken cabs from Indian Way Limo for the past 13 years, and I have found them to be very reliable. If you call them for a cab, the cab will show up! (I have found that this is not true for many of the taxi services in Hoboken). Their rates are reasonable and the drivers are friendly but not overly talkative.
The American Indian museum store offers a range of books based on their collections and a number of unusual items, also based on their collections, that you would not find elsewhere. Prices are comparable to other museum stores.
The Ganesh Temple in Flushing is a vibrant part of the thriving Hindu community in NYC. They have several deities -- Ganesh, Siva, Venkateswara, Murugan, Ram, Krisha, Parvati, Lakshmi and the 9 planets. It can be very crowded on weekends.
St. Bart's has become a NY institution. Their organ concerts as magnificent, as is the stained glass window. They have a cafe that is open, primarily in the summer, and offer a number of community events.
