LaMer Beach was my favorite place to hang out in Tel Aviv, there's music almost 24 hours a day. There are bathrooms near the restaurant as well. You can rent hookahs and relax under the the pagoda style tents. They have snacks and meals for a good price, and wonderful fruit smoothies! I love the beach, and loved the vibe of this area. Fridays are the best day to go if you want to meet people because everyone is out, but make sure you go early to get a spot. The beach fills up quick!
