Well I was frequenting Apna Bazaar as my Indian grocery of choice for basically the whole of this last summer and since. It's a decent supermarket and since it's now open 24 hrs it was open a lot later than Patel Brothers and can allow you to get basically any spice you need to randomly cook Gujarati food at 2am as I sometimes do... If anyone's followed my posting history on here you'll know that I know a thing or two about South Asian food. I'm no expert by any means, but I cook it, eat it and pretty much live it in general. Apna Bazaar is actually a rather good supermarket with a fully stocked selection of South Asian items including about 5 different brands of mustard oil (which makes me happy) and it's generally got a wider selection than the nearby Patel Brothers which is also on Hillside Avenue.
So a vegetarian friend of mine recently bought a Tarla Dalal cookbook and I took him over to Apna Bazaar to get kitted out with South Asian items. We were keeping it to a 20 dollar limit for a start up kit and so we took two bags of dal to begin with but decided we might put them back before leaving as it was quite expensive for the smaller bags (4.00 each.)
As we're doing this one of the employees comes up and gives us a little speech of "You people come in here all the time and takes things but never buy it. You just take things and look and then put them back everywhere. Please, it's a store." We pretty much brushed it off at that point and figured that confused white people have gone half-shopping in this place before but would end up not buying stuff; we, however, would be different. After that the same man proceeded to follow us and stand literally 3-4 feet away from us at all times for the next 10 minutes. Spice aisle? He's there! Getting a jar of achar? Got my good buddy right next to me for that! Fresh produce? There he is! Finally when we went back to the original aisle to put back the two bags of dal which we deemed to be overpriced our good buddy came over for another friendly and jovial chat regarding our ignorance to all things Apna Bazaar. We got something along the lines of "You people don't even know what these things are. You don't need them. You're just taking things and you're not going to buy them." We were literally about 30 seconds away from making a purchase. At this point he literally took the basket from our hands a little bit forcefully and stormed off to put everything back. We stood there in awe of what happened for a good 10 minutes discussing what happened and where we could still go at that hour (about 10pm.)
Thankfully a wonderful new 24 hour Pakistani grocery store has opened only a few blocks down Hillside near Little Neck Parkway! The prices are cheaper, the service is infinitely better (obviously) and they have almost as much as Apna Bazaar. Still, I'm never shopping at Apna Bazaar again and I'm filing a BBB claim against them. To end on a good note I do highly recommend the new store down the road. It's called something halal meat, but it's not just a butcher (though your question as to where you can buy a whole leg of baby lamb at 3am in far eastern Queens has now been answered.)
