Alcohol is one of the most expensive pleasures of Tel Aviv. Average price of a glass of wine is $10, 0,5 litre of beer - $8, cocktails are crazy expensive - $13. It's much cheaper to buy alcohol in a shop and then drink it on the beach enjoying the view (but note that it is prohibited to drink from glass bottles on the beaches of Tel Aviv, so be careful with your booze).
Still, sometimes it's worth going to a bar because there you can easily meet new people or treat yourself with a good snack. In this post, I've gathered names and addresses of the bars with great Happy Hour deals for food and alcohol in Tel Aviv.
