Steel Craft is a quirky foodie place. If the weather is nice, a nice Hawaiian Shave Ice hits the spot.

Please take a look at a map of Long Beach; it's a pretty large city, even by SoCal standards. In general, I would advise you to avoid anything directly to the West of the 710 freeway. The general area bordered by the 710 to the west, Carson St to the North and the 605 to the East is relatively safe but use common sense at all times.
My best friend's family lives by Silverado Park and operate a small strawberry stand on Santa Fe and it's a pretty blue-collar part of town.
