Not too many chefs have their restaurants by age 26, but Chef Luke Sung is never the one to take things slow. Named the restaurant after his daughter Isabelle, Sung crafts French style, classically prepared small dishes, many featuring flavors of Provence which works very well with Californian ingredients.

In France, they call the muscle that is tucked behind the stomach, and is almost next to the tenderloin, the Hangar Steak The characteristics are much like those of a beef tenderloin, and that is why it is not tough. Unlike the shanks that move a lot – it stays tender because the part doesn’t get to move that much.

The cut is a roundish, rectangular shape. Brush with olive oil, season with salt and pepper.

Grill the steak on a really hot griddle, for about 3 minutes on each side. Cooking time varies according to thickness.

Polenta Cakes Ingredients:

2. Bring liquid to a boil, add polenta. Put in a little butter and olive oil. Cover, simmer until done. Reserve until cool.

3. Put polenta in half sheet pans, or aluminum cake pan lined with parchment paper that is brushed with olive oil.

4. Take creme fraiche, and fold thickly grated parmesan cheese mixture until evenly distributed, and has a creamy texture. Spread it like icing on the cake, and cut it, and then bake it about 4 minutes at 450 – 475 degrees
