This Vietnamese store is located at the east corner of the crossing between Rhode Island Street and Niagara Street. The name A'Chau apparently means "Asia". For those intrigued by the "2" in the store's name - the owner told me that they had (still have?) a branch of the store elsewhere in Buffalo, and that this is the second branch.
A'Chau is primarily a seafood/meat grocery. Those really into seafood should check out this place sometime. There was enough specialty seafood variety on its shelves to make me wonder if they had caught, processed and bagged every creature in the Pacific, the Atlantic and maybe all the local lakes and rivers, put together. The frozen/refrigerated meat section also looked quite extensive. I am not sure what the prices were like, though.
The vegetable section had no less than 26 different varieties of south-east Asian greens (yes, I counted!). (This is a handy guide to greens:

The prices for the greens and the rest of the veggies/fruits (Cucumber, Chayote, Green Beans, Onions, Potatoes, Eggplant, Okra, Cabbage, Bitter gourd, green papaya, jackfruit, lichee, tomatoes, (sad-looking) mangoes, apples, watermelon, persimmon etc.) were at par (maybe slightly lower) with say, Wegmans. They are not as low as Guercio's which makes it hard to justify daily grocery shopping here, unless the objective is to cook specifically with those 26 delicious varieties of greens.
I was mildly bothered that the prices were not very prominently displayed and that I had to ask the owner for the price, each time I was interested in anything. He had to take the plastic bags out of the fridge and weigh them on the check-out counter to tell me what the price was. Some bags had price tags stuck on them, but it was difficult to see them well without opening the door of the fridge.
Additional attractions in this store included Shitaké mushrooms and other wild Asian mushrooms (wood-ear/cloud-ear, button, oyster), several different varieties of rice noodles/vermicilli and a million different varieties of stir-frying/cooking sauces, spice-medley-pastes and flavoured oils (I even saw a duck-flavoured sauce specifically for basting spring-rolls).
The store has a shelf of green teas, snacks similar to the ones in any corner grocery store (chips, puffs etc) but labeled in Vietnamese/French, the usual selection of southeast Asian crockery, small strange gifts, exotic snacks, soaps/detergents/cosmetics etc. As a unique touch, they had ornamental (perhaps) traditional swords in black scabbards with filigreed silver trims for about $30 each hanging by the check-out counter.
The two other oriental stores in the vicinity that I had planned on scoping out were either closed or non-existent. The "99 Oriental Food Store" [837 Niagara St, Buffalo, NY 14213] across the street from A'Chau, was boarded-up and locked. As an additional sign of dereliction, its closed glass doors were cracked with what seemed like a mob-stone-attack. The "Buffalo Asian Market" [594 Niagara St, Buffalo, NY 14201] was untraceable. If anyone has had better luck in locating this store, please feel free to add a comment.
I thought the neighbourhood was fairly safe to walk on except for a few people who seemed to think I might have a dollar to spare for them. I might not venture out here after dark though.
But then I am not (e:Robert). ;-)
I should have listened to you.
I have only had Durian on its own. It is probably much better toned down in a dish. However I suggest if you are going to try them out that you do so in a well ventilated area. I have seen durian ice cream and durian drinks at restaurants and it sounds like it might be good.
I am not sure that I saw any Durians, either fresh/frozen. But that might have been because I simply was not looking for them. There is a high chance that they might have some processed variant. You could ring them and find out -> 716-882-3867
I am just curious, have you ever used Durians for cooking? I have heard a lot about them, and might be interested in trying them out. :)
The ever elusive kaffir lime leaves, galangal, and thai basil. It took me months to find most of this in syracuse. I have still yet to find galangal here. So I suppose I have no excuse to not make a large pot of tom yum when I move. Did you happen to notice if they had frozen durians?
First of all thanks for answering my question. I admit i very picky when it comes to what food and drinks I like. But that being said I'm still trying to try new things to drink and eat sometimes. So I thought if they had some interesting drinks I might make it down there some day.
There was a fridge with some exotic sodas with Chinese/Japanese/Vietnamese/Thai text. No bubble tea, however.
I haven't been down that way in some time. But I found it odd that there where two Asian stores so close to each other. So I figured they maybe sold different stuff, now it sounds like one of them went out of business. I'm wondering did you see any Asian drinks there?
