I just had lunch at Lena's. It was a beautiful, warm, breezy date in Potsdam and the patio (with large umbrellas) was a great place to spend an hour or so. I had a Bulgarian beer (a first) and the sampler platter, which included a small salad, a paprika pepper stuffed with cheese, a delicious piece of grilled, marinaded chicken, and a battered and deep-fried ground beef kabob. But best of all was the Bulgarian "catsup," which is far superior to the American version. The servers have passable English and were friendly. However, the kitchen is a bit slow, even at lunch when there were only six other customers. The patio is a bit noisy since the restaurant faces a busy street.
