Shopping at Arash Supermarket is like going on a treasure hunt: You never know what you'll find tucked away in some corner. The bustling store is bursting with Middle Eastern items, from locally baked pitas the size of pizzas to imported and domestic feta to many types of tahini to real basmati rice. Produce here is much cheaper than at the big chain grocery stores -- lemons and limes, lettuce and tomatoes are noteworthy bargains -- as are kalamatas, yogurt drinks, pickles and olive oil. A few non-Middle Eastern ingredients, including Mexican crema and Italian lunchmeats, are also on hand. Check out the unique, commercially baked goods on the shelves near the cashiers: The exotic little cookies and unusual sweets are special treats for kids.
