Robert Grenier's letter, "Good Russian Food" (April 2), claimed that after five trips to the Soviet Union he found the food to be satisfactory. In the second paragraph of the letter it stated that the foods of Uzbekistan, Armenia, Ukraine and other republics also were featured and sampled to satisfaction. Therefore, the line above the letter should not have called the food "Russian," because they are not. Ukrainian food is very different from Russian and I am certain that Ukrainians would not appreciate having their unique foods labeled "Russian." The same goes for Armenians and Uzbeks. The line should have read: "Good Soviet Food." Russia is but one of the 15 Soviet republics.
