In a stylish setting, bandana-clad sushi chefs vigorously chop and slice at the sushi bar turning out first-rate sushi and sashimi. But for the sushi-shy, there's also an interesting limited array of other Japanese standards. Ronin offers only 5 entrées ($11-$28) but with noodles, fish, fowl and beef, most gastronomic bases are covered. The chilled green-tea noodles in lemongrass oil. Of the 20-odd beers available, nine are on tap, including Kirin Ichiban. Not surprisingly, the bar is well stocked with sake, along with an intelligently selected group of 10 bottles of wine, four of which cost between $20 and $28.
