Umi has a pleasant vibe. The menu features not only the expected sushi selections but also kitchen foods that include robata grilled meats and a couple of ramen soups.

Everything is delicious and prettily presented, to boot.

The food is modest, and the decor is drab. But if you’re in the area, it’s an inexpensive option for sushi.

Yamasan Sushi & Grill is the latest restaurant to open at Mills Park. It’s a small restaurant with a very large and ambitious menu. Besides a full offering of sushi, Yamasan has hibachi and stone grill cook-at-your-table options as well as one-pot cooking, such as shabu shabu and sukiyaki. There are seven soups and 26 each of hot or cold appetizers (not counting variations on individual items, such as the Tuna Tartare that may be ordered a la Nobu or Morimoto).

Zaru is the hip new noodle shop in Mills 50 from the James Beard nominated restaurateurs sibling team of Jimmy Tung and Johnny Tung. The restaurant occupies a smallish space with a commanding view of East Colonial Drive and specializes in udon noodle dishes, specifically the Sanuki style, the thick and dense noodles from Japan’s Kagawa prefecture.

Zen offers a tremendous deal with its tasting menu of pan-Asian cuisine. Nothing is extraordinary, but some of it is good. Be sure to sample the soups. Sushi is first-rate.
