There used to be several mehadrin pizza/bagel shops in the food area of the Tahana haMerkazit in Tel Aviv. However, I don’t know who issues those mehadrin certificates; check them to be sure. There are many glatt kosher restaurants in Tel Aviv; one of the most reliable serves haimish food and is on Rechov Mazeh (corner of Allenby??) and I believe it is called Yeshurun – the owner is Reb Zushe Rivkin, a big baal chesed. I know of 2 Chinese restaurants and a Thai place as well but I’m terrible with addresses. One Chinese place is near the water and the hotels.
