Catfish Johnny's opened last weekend at Harbor Light Marina in Lavonia.  I went with a friend and was pleasantly surprised.  The food and the service was above what I would expect for the first night at a lakefront restaurant.  I had a blackened tuna-steak sandwich which was cooked to the appropriate medium-rare with a side of onion rings, and  Ed had the buffalo chicken sandwich with spicy slaw.  The menu was limited but about what you might expect for lakefront dining.  No salads yet, but I hear the menu will be expanding soon.  The best news is the restaurant has dedicated boat slips, and you can spill over to the gas dock after hours.  You can even order your food to go!  Hope to see you there.
