Nope, but now I am gonna have to go check that out! I love Rodgers Park.
I work out in los suburbios, the frutería I go to by my work is Farmer’s Pride on Algonquin in Arlington Heights. I meant to go there every single stupid day last week and pick up some avocados, but I was completely swamped with work and couldn’t sneak off for some produce shopping.
Sorry! I’m one of the poor lost souls owned by AT&T 
I’ve found that Iowa actually has a surprising number of ethnic groceries. I have several Asian co-workers who have pointed out the good groceries and restaurants to me (and they often bring great stuff to potlucks, too).
Even here in Des Moines we have a whole bunch of Chinese and Thai groceries, countless Mexican groceries, two European groceries (one eastern European and one more “yuppie” Western one), a Filipino grocery in one of the malls, and a wonderful Indian grocery that I thank my lucky stars exists. Even Ames has several Asian grocery stores, including one on campus that caters to international students.
I often make the rounds to these places when I have a day off. I used to be uncomfortable when I was younger, but now I don’t mind anymore; I’ve never had a bad experience.
Produce is often cheaper and better, and ethnic ingredients are a fraction of the price as the upmarket groceries that might have them. I often get pre-packaged Indian curries, fresh okra, whole spices, rice in bulk, ramen, and whatever strikes my fancy. Everything’s cheap! I usually will pick up one item that I’ve never tried before if I can reasonably assume it’s not part of an animal. (Grass jelly juice, ew.) I bought a spice grinder, too. I bought some Thai sticky rice so I can try making it at home also.
Anyone in Madison, WI? I went to college there and fell in love with the internation supermarket on… Park, I think? Those sesame-mung bean balls… oh man. Finally found them again after years of pining at the Des Moines farmer’s market. Just once. Sigh…
I love ethnic grocery stores. If you don’t go and you’re a foodie, you’re missing out.
Since we have a number of Chicagoland posters in the thread, I’ll throw out the Maxwell Street flea market for a cheap and widely varied source for produce. I went for the first time around Thanksgiving and can’t believe I’ve lived my whole life in Chicago without having been there before. Lots of great non-food items, too.
I’ll echo what lots of people in this thread have claimed–you can get fresher produce, different varieties of foods, etc. for more quality and lower prices than mainstream supermarkets. Also, I found cuts of meat at the supermercado that I can’t find at my regular supermarket. I bought some flank steak for fajitas tomorrow night and I couldn’t find it at my local Harris Teeter.
Have you been to the Farmer’s Market in Nashville? All kinds of various ethnic foods for sale there (they even have a store that sells nothing but hot sauces!).
