On the edge of Garden Grove’s Korean Business District, auto dealerships, cafes, and day spas dominate the landscape. But a strip mall at Brookhurst Street and Garden Grove Boulevard stands out for its quiet, low-key atmosphere—and for its newest tenants, a seafood restaurant and a gelato bar.

Submarine Crab

Try Vietnamese Cajun-style seafood—such as king crab legs, crawfish, shrimp, and clams (market price), along with Cajun stirfry ($9)­—at this spot that looks like a submarine, portholes and all. 10130 Garden Grove Blvd., 714-534-9888, submarinecrab.com

Frozen Bar

The house-made gelato comes in traditional flavors, such as pistachio, but also in fun ones such as Shirley Temple and Thai tea ($3.75 for two scoops). Have some folded into a doughnut ($5), topped with cereal (50 cents), or as a pop ($3). 10130 Garden Grove Blvd., 714-462-1720, frozenbar.net

East West Shabu Shabu

At this DIY restaurant, the thinly sliced meat and seafood come with plenty of veggies, miso or sukiyaki broth, and peanut and ponzu sauce ($11 to $30). If you’re a shabu newbie, friendly servers will help you cook it up. 10130 Garden Grove Blvd., 714-590-6129
