I have been to Kefalonia 4 times, each of these times to Lassi. This is because of the clean beaches. On the main road of Lassi, there are a lot of restaurants, the Fanari road has 5 restaurants, if you walk this road you will come across these, the first being, stopsito, the second Chinese dragon, third, Oskars, forth, thalasomilos and last venaries tavernas. Oskars is the best taverna in kefalonia, because it has a very nice balcony, with a mixture of flowers, a very nice sunset, a very big bar and a very big dance floor. Very, very good food, service, and very Greek entertainment. I recommend to every body to go to Oskars. 
If you like the Greek entertainment and best food , go to Oskars, if you don’t like it, then I would not recommend it. Oskar makes Greek tricks and Greek blah blah all night, because he wants every body to smile and enjoy their time with him. Oskars restaurant/bar is an original, Greek place.
P.s: we recommend to you that you walk the fanari road to see the best view, and go to the lighthouse so you can have good memories and get some memorable photographs.
p.p.s: the fanari road starts in lassi and carries on past the lighthouse through to Argostoli Square, it is the connection road.
