So this review is probably a little biased (cuz shopping here reminds me of the awesome time i lived in Oaxaca, Mexico), but still; teee-rust me, Ranch Market is full of life and great produce and makes grocery shopping just a lil more fun:)
I usually make sure I go on Wednesdays where produce is ridiculously cheap...like 7 kiwi's for a dollar or 9lbs for a dollar watermelon...I'm not gonna lie, I have posted my receipts on the fridge with pride...these are my "A" graded school papers of adulthood. The only issue is that when I come home with a trunk full of fresh fruit and veggies that cost me $8 I slowly realize I have to actually store and eventually eat all of the produce I just bought. I hear Thursdays are the days to buy meat for cheap--but my fridge is usually busting with pineapple and strawberries by that point and there isn't room for an ounce of carne asada.
long story short, be prepared to weave through the masses on Wednesday mornings for some great finds. The rest of the market is fabulous as well. The "Tradiciones" restaurant serves excellent--and cheap (shocker) authentic Mexican food. Plus they also have an aisle with cooking supplies (like giant blue pots, tortilla presses, molinillos etc) and a whole wall of spices.
enjoy:)
