A 50% increase in tourists is highly optimistic. There are some good deals around, but not if you're eating out on the sea front at Balchik, generally. There are a few tourists around in Balchik, but nothing like the numbers of summer 2007, 2008, although 2009 was even worse at this time, so looks as if there are some improvements. Some restaurants are offering deals such as fish and chips, a drink and a good dessert for 13.00 levas, which is is not bad, but others are still offering a 300 gm fish dinner for upwards of 20 leva. Wise to shop around.
