Few places offer as much German Old World charm as Kegel’s (5901 W. National Ave.), with its congenial bar, wood tables, hunting murals, stained-glass accents and oak beamed ceilings. The menu is very German, though the Friday fish fry competes for popularity. The item to order is sauerbraten; the tender beef is marinated for 10 days before it’s served. You won’t find any shortcuts here. Instead, you’ll find beef rouladen and a good Wiener schnitzel at moderate prices. For the fish fry, try the bluegill or the lake perch.
